Hey all, I was wondering if someone could explain the difference between isothermal and adiabatic processes. I know that in isothermal process, there is no temperature change in the system, and in adiabatic process, there is no heat transfer. However, can someone explain to me what each one is specifically, and the difference? Also, why is it that if you take canned air (the types used for computers) and turn the upside down, the liquid that comes out is freezing cold? I know that the liquid that is normally at the bottom of the can will come out first, but why is it cold? Thanks!
