Question

Define specific heat of a gas at constant pressure. Derive relation between C and cu (See Lesson 10)


​

Answer 1

Explanation:

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. ... dU = CV dT and CV = dU dT . When heat is added at constant pressure, we have QP = CP △T = △U + W = △U + P △V .
