Explanation:
Detailed explanation-1: -The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00 ºC. The specific heat c is a property of the substance; its SI unit is J/(kg ⋅ ⋅ K) or J/(kg ⋅ ⋅ °C °C ).
Detailed explanation-2: -4184 joules of energy is needed to heat one kilogram of water by one degree Celsius, but only 140 joules is needed to heat one kilogram of mercury by one degree Celsius.
