The specific heat
is the amount of heat
per unit mass required to raise the temperature
by one degree Celsius
. The relationship between heat and temperature change is usually expressed as follows:
Q = C * M * delta T
Q = Heat
C = Specific Heat
M = Mass
Delta T = Change in Temperature
The relationship does not apply if a phase change is encountered, because the heat added or removed during a phase change does not change the temperature.
Note that 1 degree Kelvin is the same as 1 degree Celsius, it is the number of degrees that changes that matters.
Specific Heat is also commonly known as Specific Heat Capacity.
