Heat Capacity of Gases

Postby Alexandra Carpenter 1G » Wed Jan 17, 2018 9:01 pm

What do the equations Cv,m = 3/2R and Cp,m represent or calculate? And when would we use them?

The equation Cv,m=3/2R refers to the molar heat capacity for an atom/monatomic gas at constant volume. Pg 281 of the textbook has some good info on it and a nice chart haha

Cv, m = 3/2R is the equation used to calculate a heat capacity for atoms or monotomic atoms at a constant volume. Cp, m = 5/2R is the equation used to calculate a heat capacity for atoms at a constant pressure. The R represents the gas constant, R = 8.314 J/K*mol.
