Enerjiya di gaza îdeal a monatomîk de
Enerjiya di gaza îdeal a monatomîk de, tevahîya enerjiya kînetîk a wergerandinê ya molekulên gaza îdeal a monatomîk e. Tevahîya enerjiya kînetîk a wergerandinê ya molekulên gaza îdeal = berhema enerjiya kînetîk a wergerandinê ya navînî ya her molekulê û hejmara molekulan (N). Bi awayekî matematîkî:

U = Energy in a monatomic ideal gas (J)
N = Number of molecules
k = Boltzmann constant (k = 1.38 x 10-23 J / K)
T = absolute temperature (K)
n = Number of moles (mol)
R = universal gas constant (R = 8.315 J / mol. K = 8315 kJ / kmol. K)
Energy in a diatomic ideal gas
Energy in an ideal diatomic gas is the total amount of translational kinetic energy, rotational kinetic energy and vibrational kinetic energy of the diatomic ideal gas molecules. By the principle of energy equipartition, the energy in an ideal diatomic gas is:
![]()
Energy in an ideal polyatomic gas
Energy in an ideal polyatomic gas is the total amount of translational kinetic energy, rotational kinetic energy and vibration kinetic energy of polyatomic ideal gas molecules. By the principle of energy equipartition, the energy in an ideal polyatomic gas is:

Energy in real gas
Energy in real gas also depends on temperature. When real gas pressure is large enough (small real gas volume), real gas starts to show deviant behavior. Therefore, it can be said that energy in a real gas also depends on pressure and volume.
