CP-T curve covers 10 J from 2^oC to 10^oC, what is the enthalpy change?

A. 10 J

B. 20 J

C. 80 J

D. 100 J

This question was posed to me in unit test.

I need to ask this question from Heat Capacity Equations in portion Introduction to Energy Balances for Processes without Reaction and Calculation of Enthalpy Changes of Basic Chemical Engineering

The correct choice is A. 10 J

Easiest explanation: Enthalpy change is the area covered under CP-T curve.
