Question

4. It takes 7.8 kJ to raise the temperature of a 2.78 kg sample of an unknown substance by 12 C.
Calculate its specific heat

Answer 1

E=mcT
E is the energy transferred in joules, J
m is the mass of the substances in kg
c is the specific heat capacity in J / kg °C
T is the temperature change
7.8=2.78*12*C
C=7.8/2.78*12
