Lukas Doyle · Answer 1

In getting the heat capacity of a substance you must first consider the mass, specific heat of the water and also the change in temperature of the substance. And the formula in getting the heat is:

heat is equals to the product of mass, specific heat of water and the change in temperature. and the answer is 13.14 J
