**Specific Heat Capacity**

Specific Heat Capacity of a substance is defined as the amount of heat required to increase the temperature of unit mass (1 kg) the substance through one degree Celsius.

Its unit is kJ/kgK

Specific Heat Capacity is denoted by C

**Specific Heat Capacity at constant volume**

Specific heat capacity at constant volume is the amount of heat required to raise the temperature of a unit mass of a substance by one degree celsius at constant volume

Q = m.C

_{v}.dT

where

Q is the amount of heat transferred in Joules

m is the mass in kg

C

_{v}is the specific heat capacity at constant volume in kJ/kgK

dT is the difference in temperature in K

**Specific Heat Capacity at constant pressure**

Specific heat capacity at constant pressure is the amount of heat required to raise the temperature of a unit mass of a substance by one degree celsius at constant pressure

Q = m.Cp.dT

where

Q is the amount of heat transferred in Joules

m is the mass in kg

Cp is the specific heat capacity at constant pressure in kJ/kgK

dT is the difference in temperature in K
