Four Difference between Real Gas and Ideal gas
Answers
IDEAL GAS: The gases which all follow gas laws at all given temperature and pressure are called Ideal gases. No gas is Ideal, this concept is hypothetical.
REAL GASES: The gases which follow gas laws under certain temperature, pressure, volume conditions are called Real Gases. All the gases we know are real gases.
Some gases behave nearly like ideal gases at high temperature and low pressure.
Hope it helps you !
hey mate ,
here is your answer :)
""""""""""""""""""""""""""""""""""""""""""""""
Ideal gas
1.obeys ideal gas equation pV = µRT at all temperatures and pressures.
2.The volume of the molecules of an ideal gas is zero.
3.There is no intermolecular force between the molecules.
4.There is no intermolecular potential energy (U) because intermolecular force (F) is zero.
5.It 15 has only kinetic energy.
6.At 12 absolute zero, the volume pressure and internal energy become zero.
Real Gas:
1.It 29 does not obey pV = µRT at all values of temperature and pressure.
2.The volume of the molecules of a real gas is non-zero.
3.There is intermolecular force of attraction or repulsion depending on whether intermolecular separation is larger or small. Potential energy (U) does not equal to zero as intermolecular force (F) is not zero.
4.It 13 has both kinetic and potential energy.
5.All real gases get liquified before reaching absolute zero. The internal energy of the liquefied gas is not zero
