Specific Heats, Internal Energy and Enthalpy of an Ideal Gas

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
