Question

The specific heat at constant pressure is given by the expression ____________

(a) CV = dq/dT

(b) CP = dq/dT

(c) CV = dqdt

(d) CP = dq/dt

This question was addressed to me during an internship interview.

This interesting question is from Thermodynamics Applications topic in section Thermodynamics of Chemistry – Class 11

Answer 1

Correct option is (b) CP = dq/dT

To elaborate: As we know that dq = CdT; where q is the heat energy, C is the specific heat and T is the temperature. At constant pressure, specific heat is given as CP. The specific heat at constant pressure is given by the expression CP = dq/dt.
