Question

Prove that specific heat at constant pressure is always greater than specific heat​

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. QV = CV △T = △U + W = △U because no work is done. Therefore, dU = CV dT and CV = dU dT .

Answer 2

Answer:

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

Explanation:

QV = CV △T = △U + W = △U because no work is done. Therefore, dU = CV dT and CV = dU dT
