To raise the temperature of a 2.0-kg piece of metal from 20ºC to 100ºC, 61.8 kJ of heat is added. What is the specific heat of this metal in kJ/(kg.K)?

Question

Question 1 options:

A) 0.39

B) 0.31

C) 1.6

D) 1.2

E) 0.77

Answer 1

Familiarize yourself with the definition of specific heat:
C = (heat added)/[(mass)*(temp. rise)]

In this case, that would be
61.8/[(2*80)]

Do the calculation and make your selection.
