The quantity of heat required to raise the temperature of unit mass of a material by one degree centigrade is called
Specific Heat
Therefore, the heat required is equal to the specific heat capacity. While specific heat is defined per unit mass, the total heat capacity of an object is the total amount of heat required to raise the temperature of that specific object by one degree.
Important Questions from The Perfect Gas
The heat that must be absorbed by ice of mass 500 g at – 10°C to take it to water at 20°C is (Specific heat of Ice is 2.2 kJ/kg K, Specific heat of water is 4.2 kJ/kg K and Latent heat of fusion of ice is 300 kJ/kg)
2 kg of substance receives 500 kJ and undergoes a temperature change from 100°C to 200°C. The average specific heat of substance during the process will be
The general law for the expansion or compression of gases is:
SI Unit of Specific heat capacity is
Sl unit of specific heat capacity is
