Cyclohexane having CP = 48 J/^oC, is heated from 50^oC to 55^oC, what is the enthalpy change?

A. 240 J

B. 480 J

C. 720 J

D. 960 J

The question was asked in an interview for job.

I’m obligated to ask this question of Heat Capacity Equations in chapter Introduction to Energy Balances for Processes without Reaction and Calculation of Enthalpy Changes of Basic Chemical Engineering

Correct answer is A. 240 J

Explanation: ∆H = 50∫^5548.dT = 48*5 = 240 J.
