Phase Changes endo/exo

Postby Emily Vainberg 1D » Sun Jan 26, 2020 2:00 pm

Are any phase changes exothermic? All the ones we went over in class were endothermic.

I believe freezing and condensing are exothermic. Hope this helps.

Yes some phase changes are exothermic, as long as it is releasing heat.

Yes, some phase changes are exothermic. If you go from a system of higher energy to a system of lower energy, it will be an exothermic reactions. For example, going from a gas to a liquid in vaporization (or commonly called condensation) reaction, it is exothermic because the gas has a higher energy which must be released along with the formation of the liquid.
