Question

Reversible heating of perfect gas at constant pressure is not correctly explained by

Answer 1

The heat capacity at constant pressure CP is greater than the heat capacity

at constant volume CV , because when heat is added at constant pressure, the

substance expands and work.

When heat is added to a gas at constant volume, we have

QV = CV 4T = 4U + W = 4U

Answer 2

Answer:

w<0
