What happens to batteries when they come into contact with the heater? Why do they release their last energy reserves? I thought the voltage of galvanic cells drops at higher temperatures?

Loading...Hello dear people, I would be interested in the topic of PPE and self-protection: is a glass or polycarbonate visor recommended when operating a melting furnace (I only have a small 2 kg furnace) and the associated casting of metals? At the moment I'm leaning towards a glass face shield because I think that if…
Hello, Is the number of electrons in Niels Bohr's shell model correct (the shell model only refers to the main groups, not to the side groups)? K shell: 2 electrons L-shell: 8 electrons M shell: 8 electrons N-shell: 18 electrons
How can soap formation be represented in reaction equations? Thanks in advance.
I'm currently taking a chemistry high school exam and am wondering if mercury can react with gold oxide. I know that mercury has a stronger bond to oxygen than the gold in gold oxide. However, this bond between mercury and oxygen is very weak. Can mercury and gold oxide still react with each other? Thanks…
Wrong thought! The Nernst equation provides a direct proportional relationship between electrode potential E and absolute temperature T.
but if both half cells have a larger potential, they still fall
If the normal potentials of the half cells have different signs, rather not.
The batteries have a gelled electrolyte. If you heat it, it becomes a little more liquid and the battery provides more voltage for a short time!
when you do it in mixer, the energy is free.
