capacity for heat. In fact the full name for specific heat is specific heat
capacity.
6
The amount of heat necessary to change the temperature of a given
amount of a substance depends on three factors: the mass (m), the specific heat
(designed by C), and the temperature change (T). In equation form we write
amount of heat to change temperature = mass specific heat temperature change
H + m c T

The amount of heat necessary to change the temperature of a given
amount of a substance depends on three factors: the mass (m), the specific heat
(designed by C), and the temperature change (∆T). In equation form we write
amount of heat to change temperature = mass ⋅ specific ⋅heat temperature change
H + m c ∆T
