Cv,m and CP,m

Postby Douglas Nguyen 2J » Thu Feb 07, 2019 9:29 am

What is the difference between CV,m and CP,m? What do they signify aside from being the heat capacity of gasses?

C v,m signifies the specific heat capacity of a gas at constant volume per mole, and C p,m signifies the same for constant pressure per mole.

also, Cp,m will be larger than Cv,m because at constant pressure the system is allowed to expand so the some of the heat is used to do work. on the other hand, at constant volume the system cannot expand.
