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
