Internal energy
The association of energy with random molecules who move in disordered motion is known as internal energy.
Specific heat
Every matter has a certain temperature that is related to that mass. The amount of heat that is required to increase the temperature of a mass by one degree Celsius is known as specific heat. The heat amount is calculated on the basis of per unit mass.
Enthalpy
A system’s total heat content (equivalent) thermodynamic quantity = enthalpy
As per this, it is the result of the sum of volume and pressure,and a system’s internal energy.
Its equation is depicted as,
H=U+PV
Where,
- PV is pressure and volume
- U is internal energy
- H is enthalpy
