Hi everyone,
I know that the temperature decreases in the adiabatic expansion of an ideal gas due to the work on the surroundings. However, one of the EK 1001s seems to say that when a gas expands at constant pressure, the temperature increases because PV = nRT (V increases, so T has to increase). Are these two both true (can they both be true)? They seem to contradict each other.
Thanks!
