Different substances have different specific heat capacities ­ the amount of energy needed to raise the temperature of 1.0 g of a substance by 1.0 C.
See the backside of the Periodic Table for these values.

There is a formula to calculate the amount of energy absorbed/released by a substance (when there is a temperature change)...
q = mc t (also q = vc t )
t = change in temperature
q = amount of heat c = specific heat capacity If you are using specific heat capacity of
WATER, you can use these units as well.

EX # 3
By removing 2.40 KJ of energy, the temperature of a substance is lowered from 28.1 C to 14.6 C. Calculate the heat capacity if there is 1.6 Kg of the substance.
