Hey:) I have to do the above physics problem and I really don't know how to calculate it. Can someone help me or explain the problem to me?
Why can't energy be added to an electron?
In one of the first episodes of the podcast "The Great Mysteries of Modern Physics," it was stated that electrons cannot be given energy because they have no internal structure. Unlike neutrons and protons, which consist of quarks. Why is an internal structure needed for this? Second, I have a problem understanding this. If an…

I'm asking this for a physics paper on coal-fired power plants, where I have to explain how they first appeared and were formed. However, I can't find anything about it on the Internet. I would be happy to receive answers, if possible with source information :))
Heating with gas is cheaper and particularly favorable in winter, because the efficiency of the heat pump in winter drops to 1:2.
Gas costs 12.5 cents/kWh and electricity 36 cents/kWh, you already need an efficiency of 1:3 so that it costs the same amount. In autumn and mild winter you will come to the same heating costs.
The installation and maintenance of the gas heating costs much more. For me, the heat pump is worth more than the gas heating.
If you have a lot of PV on the roof, it is possible to cover a part of its heating costs in winter.
With me, my landlord determines the basic type of heating.
In summer, however, with my small PV system + pool micropump I can hit three flaps with a fly.
– Almost free
– Hot water in the tub
– Cold air and room dehumidification in another room
Depends on your argument: cheaper or more sensible!!
From a KW power you get exactly 1 KW of heat – no more. There we would be in the argumentation of heating fans, heat waves etc – depending on the use and costing this can count. Installation costs are minimal. Maintenance costs practically equal to zero.
Heat pump – you get more KW out than you use KW. but you have to make or change installations that drive the price (always long-term). There are also maintenance costs – I don’t know right now. A tenant gets the one that’s just flipped, but a homeowner has to pay for himself.
Gas: similar, but you usually don’t need to change the installation. means: more unambiguous (long-term) price advantage, but maintenance costs and, in addition, spiders of politics.
If you look at the situation (political, economic) critically, you can see:
Nevertheless, if you have possibilities to keep the electricity price under control by PV or anything else, it’s okay. How to use it (WP or IR) – other construction site.
Gas / oil is not the future. However, permanent electricity imports are not.
What’s up? You always have to count for about 20 years. Not only at the moment, otherwise the investment and maintenance costs fall under the table.
Right now: first look at what the next government is doing.

Where did you get your wrong number to the electricity imports?
If you look at the higher installation costs for a heat pump, the heat pump is the better choice. Gas and oil will definitely become more expensive, the price of electricity should remain stable and fall in the long term.
Heating with a heat pump already costs about 30-40% less than comparison with gas.
So right ahead, a heat pump does not heat with electricity. It heats via heat exchange and temperature difference. The current is required for operation of the WP but not directly for heating.
The pure heating is significantly cheaper with heat pump in almost all cases. In comparison, much less electricity is required than oil or gas.
In addition, however, there are also the purchase costs, which are usually higher than in gas or oil heating. If necessary, heating elements must also be exchanged. Here you can’t call a flat-rate number because this is different in every building.
Right. The promotion drastically reduces the purchase price to virtually equal.
Heating with heat pump is cheaper.
Current current price approx. 30 ct/kWh
Current gas price approx. 10 ct/kWh
Ratio about 1:3, but heat pumps operate in the annual average at about 1:4, i.e. with 1 kWh of electricity, 4 kWh of heat are produced. In addition, the CO2 price shares in gas, i.e. gas becomes more expensive, but the electricity from wind power and PV tends to be cheaper.
Heating with gas – unambiguous. On the one hand, the purchase of a gas heater is significantly cheaper and on the other hand I get a kW/h gas for 8.4 cent. Electricity always costs over 32 cents per kW/h. Only at an efficiency of four, which only create the latest equipment, are they at the same cost. Only then must the house be designed for heat pump (low flow temperatures, underfloor heating, large heating surfaces).
However, as soon as I have my own solar system and get my electricity for free, the ratio changes.
The stupid thing is, I need the heater when it’s cold outside. So in winter. Since the heat pump has a poorer efficiency and solar energy (PV) is also not available.
So gas heating is cheaper than heat pump.
There are mistakes in your argument.
You forget the efficiency of your gas heating. And the improvement of insulation etc. helps both types of heating and you can not only load the heat pump.
You can sell the electricity and buy it in winter.
Don’t let you laugh! I wanted a gas heater in my NEW house! What did I have to do to get it approved? Double thick walls! Triple glazed panes, double insulation on the roof. I had to make 36.5 cm thick walls. In addition with heat insulation plaster. On top of the roof also a 200 layer of insulation. The neighbors who heat with a heat pump needed only 25 cm walls. Why? Because I’m using CO2. Really! Because I don’t take “green” energy for heating! Really! That was the reason. But okay, now I’ve got a very isolated house and I’ve got a gas!
Understand, heat pump is not to be used when insulation is missing.
It’s like most of them.
Well, you can do that for a while.
Maybe now. Five years ago, when I planned it, it was different. Nevertheless, I have just completed a gas contract for 5.4 cent/kW/h. For another year.
My solar system on the garage produces about 9 MW/year. This is convenient for the house and the e-car. To heat it is too little, especially because I need the energy in winter. But I prefer to sell the superfluous energy for 8.3 cent per kW/h and buy gas for now 5.4 cent if necessary.
You’ll get the pre-running temperature well with a WP.
Nothing has to be changed. Like at -15° C, you have a working number of 3.
A monoblock WP costs 13,000 + 19% minus 50% with all the Schnickschnack. Then you’ll get under 8,000 €.
They are similar to those in calorific devices.
Part, part. Partial rib heaters, partial floor heating. Bathrooms have underfloor heating, living room radiators, as I place carpets and upholstered furniture. The gas heating itself came a little over 2000 euros.
The flow temperature is 45 degrees. My house, I’ve already written it up, is now 4 years old.
And the maintenance costs? If what’s broken?
I’m talking about the heat pump.which costs after promotion around 9,000. And works with the radiators. Unless the pre-blue temperature is 90°. When is your house? rib heaters?
In the full price? With 14 radiators for a detached house? Three floors? With two bathrooms? With laying, piping, cabling? Really? Where?
You come to about 9,000 euros for a new WP. And it lasts as long.
I paid about 9000 euros for my gas heating. All taken together. The WP would have cost 24,000. At least four years ago.
I’d have to get the money in first. In addition, gas heating lasts 15 to 20 years. A WP 8 to 10 years (in the best case)
And why not with WP?
The logic is: if you heat sustainably and not climate-damaged, the consumption is your thing or your purse. It doesn’t hurt the public.
No, the newer WPs are loosely clear at 60° temperatures.
Of course, insulation is always better. But you would also reduce gas consumption
This depends as always on us, with gas is significantly cheaper.
Heat pump delivers too little and costs too much electricity, supplementing with heating fan is even more expensive as my neighbor is experiencing. His tenants are freezing.
A kWh of current costs 32 ct, gas 11 ct. The WP has a working number of 4, the gas heating of 0.9 at most.
So 32 / 4 =8 ct, 11 / 0.9 = more than 12 ct.
The WP therefore costs 66% of gas, falling perspective.
You compare apples with pears. On the one hand, a heat pump has no efficiency of 4, at least not at minus temperatures.

You’re happy when you get on the double. Second, modern gas heaters have efficiency of almost 100% (95 to 99)
https://www.thermondo.de/info/rat/comparison/effectiveness of heating/
And my gas costs only 8.4 cent /kW/h
And why are many tenants freeze when sun Kram was installed, my neighbor has just purchased for 10,000 EUR heating fans, and also solar on the roof.
Unfortunately, you need the heating all the more if it’s really cold. In the other time, my solar thermal heats my heating free of charge. Well, almost free, the small circulation pump needs a little electricity.
The number of benefits may be below 4 weeks a year, for which it is over 4 on 16 weeks.
The efficiency of gas heaters is in the range you mentioned, you forget the gas coefficients.
Wow, that’s 200 fan heaters? Then he needs his own power plant. 400 kW!
In 2027, the EU has a wide emissions trading and the Co2 price is now the 5 specialist of ours.
that hits with about 6 cent / kWh on the gas costs, that is stand now and we know that the Co2 price continues to rise
I’m sure the Christians will get him back.
WP is cheaper. Especially in the future.
If the electricity price continues to rise in the future certainly not.
The electricity price from renewables falls in perspective.
Okay, let’s wait.
See – You don’t recognize “the relationships”.
Don’t do anything, I’m sure you won’t try to explain it again, if you don’t get it, then you’ll have to stick to your ideology until everything will come together like a card house over you.
What does Trump have to do with it?
As if you’d recognize the “columns”…
Where and how is your connection to know when you think of Trump & Co?
No, I’m really mad. Give money for nothing and nothing again, an absolute pork. It is surprising that there is more and more consent for the AfD….
According to many installers, it’s not possible for me at all, but you’ll find it just “Spinnerei”.
So I can only hope you won’t force me to do that.
Oh, leave it. It has no purpose to discuss with someone who does not want to understand the connections.
Don’t use WP and I’ll change your behavior. And don’t worry about rising prices or weather disasters afterwards.
No, you just don’t want to see the truth in it.
What is “combined talk” for you, we experience citizens month by month in our rising overcrowded accounts of the energy groups – for me absolute madness, if you really mean it seriously with the goal – that is, the energy transition.
It’s a mess.
To abolish them, an incentive no longer to install a plant.
The cause of high prices is generally only the Gier after more money the “environmental aspect” seems always only advanced.
The ugly current-producing wind turbines are a different but also absolutely relevant issue.
Want money and have to earn everyone. Go on.
The feed supplement is a cause for higher electricity prices. The TSOs are remunerated via the market price without feeding.
I’m really excited about it, so on your perspective
It is also good that the feed-in feed on PV systems should be completely deleted when the greens should get through again.
It is a total incentive to dispense with solar systems. A total of such a measure serious an energy transition.
I am in favour of a regeneration of the green party in the abyss of the Bundestag – but I am also quite in opposition…
Well, soon we know more….
gas
heat pumps are still running
…and what for. I’m just looking for big minus temperature figures.
:
What defects? Now have three houses that are heated with WP and there have been no unplanned failures since 2015.
Thanks for the hint. Hopefully, one day the haunt is over.
Warmth will always be cheaper because gas gets more and more conditions and CO2 emissions.
But the electricity is always more expensive…
Why is electricity becoming more and more expensive in Germany? Because the price of electricity is determined by the price determination method (Merrit or Procedure) not as an average of the purchase prices but by the most expensive purchase price (and that is gas). The electricity companies make the bags full because they use a lot of favorable wind and PV electricity, and about 25% gas electricity shopping “must”. But the electricity is sold as if 100% gas were purchased. A schelm who thinks evil.
Then only the right house has to be found, but most of them do not.
This will increase prices even more.
Ms. Merkel was a power politician.
Today, fortunately, she was retired, for example, always for atomic current, wanted to keep the existing plants running over their agreed running time – she is now – as written – retired and this is mM very good.
Whether we are climate-neutral, it doesn’t matter if all the other nations won’t. We get the problems additionally free house, although we are “climate-neutral”, so or so.
The sooner we are finished, the worse it is for our already strong economy. The foreign country continues and laughs over us only.
You will see how we stand economically when the distribution of further social welfare and the economic green descent continues.
You can only spend what you’ve done. We generate less and less year after year and worship from the past you seemingly despised strong economic time with coal and cheaper energy.
The green ideology brings us – and only us – faster into unemployment, poverty and misery than we are aware.
Climate protection here in Germany/Europe, which does nothing, does not take advantage of us all, even if many do not want to see it.
It’s not the fault of the Greens. Mrs Merkel has rightly stated that Germany should be climate neutral. There is also no alternative because we only have this one planet to live.
The currently +1.6°C global warming is unfortunately not yet the end and at +2°C will be as storms as they met last weeks Ireland and England have a regular, almost monthly “event” and the only way to permanently limit it is away from burning fossil fuels.
That’s uncomfortable, that’s expensive, but the later we react (because it doesn’t get so bad) the more incisive and massively expensive it gets. I may still experience abandoning the 10 to 20km coastal landscape because we have taken the necessary measures too late and too hesitant.
If anyone tells, “Climate protection we don’t need to be too expensive to doof” that turns into a series of Trump who tells that the US tariffs are paid by China and Canada.
It does not remain when it goes after the greens – but perhaps the haunt is finally over on 24.02.
The CO2 tax is currently 3ct/kWh, which should be usable.
You forget the legally required climate impact, these price increases are simply wanted by politics.
Everything to despair….
