Why doesn't the Earth's interior cool down?
Should radiate into space and therefore cool down
North or south pole on a coil?
Hello everyone. Could someone help me with this task? Thank you.
Interaction principle?
ByViDa1111
Hello, The principle of interaction assumes that every force has an equal and opposing force. This can be applied to many everyday examples, such as driving a car. However, one thought experiment remained unanswered for me: Let's imagine a person exerts enough muscle force to push a car. The person has less mass than the…
Did Albert Einstein really only get a 4 in math?
This is what they always sing at Schloss Einstein: "Even Einstein only got a 4 in math and later became a total genius…" Do you believe this song?
Speed of light?
Our solar system moves through space at about 800,000 km/h, but if a flashlight is switched on on Earth, it can be measured over a certain distance that this light travels at almost the speed of light. Shouldn't the speed at which our Earth moves through space be adjusted to the speed of light on…
If all Germans opened their windows and switched on the lights, would it get warmer?
So let's say all Germans open their windows at the same time and turn up the heat. Would it get warmer across Germany, or at least in crowded streets? So at least 0.1°C?
the freezing point is below normal pressure at 0° C.
On the moon this is different, there is no atmospheric pressure, so nothing that the H2O molecules would keep together, therefore the water directly sublimes to gas and does not freeze, the gas is split up by the hard radiation and deflutes due to the weak attraction of the moon quite soon into space.
And yet I read in m connection with the moon landings of any water in moon craters now planned by various actors. Is that possible?
that is correct, on the moon there is ice in shaved craters, water is also included in the Regolith, but the water is not frozen there but has already arrived as ice.
the Mare are not an impact crater, these are lava levels from the time of origin to say a melting crust.
Otherwise, you are right with their explanations, with the guesses too.
Asteroids hit on the moon. The so-called “Mare” are all the impact craters. Comets would also be conceivable. They’re not called “dirty snowballs” for free. Also in the formation of the moon, enclosed in rocks could have reached the moon from the earth (but this is only a guess on my part – no idea whether one has already carried out corresponding investigations on the “moon water”.)
does it also, but only minimally, ice has a crystalline structure and under these conditions does not manage the phase transition well, except it is melted, then it is fixed.
But shouldn’t this ice sublime and disappear as a gas? How come this ice is stable?
Who brought the ice?
