Cp vs Cv

Postby Rian Montagh 2K » Fri Feb 08, 2019 11:08 pm

What do the different subscripts mean for the heat capacities, such as Cp and Cv?

Cp means constant pressure and Cv means constant volume. They are both associated with molar heat capacity of an ideal gas. Cv=(3/2)(R) and Cp=(5/2)R. R is 8.314J/mol*k
