Specific heat is the amout of heat energy required to raise the temperature of a unit mass of a substance by a unit of temperature (1 Kelvin or 1 degree celsius)
When a substance has a high specific heat (Cp), it means that a large amount of heat energy is required to increase the temperature of a unit mass of that substance.
Example of a substance that has a high Cp is water with a specific heat of 4200 J/Kg°C
Example of a substance with a low Cp is Iron with a specific heat of 0.45J/g°C
