Difference between ideal gas and real gas |
| Answer» \tIdeal gasReal gasIdeal gas obeys all gas laws under all conditions of pressure and temperature.Real gas obeys gas laws only at conditions of low pressure and high temperature. They obey Vanderwaal’s real gas equationThe molecules collide with each other elastically.The molecules collide with each other inelastically.The volume occupied by the molecules is negligible as compared to the total volume.The volume occupied by molecules is not negligible as compared to total volume.There are no intermolecular forces of attraction.Either attractive or repulsive forces are present between the particles.It is a hypothetical gas.It exists in nature around us.It has high pressureIt has a pressure correction term in its equation and the actual pressure is less than ideal gas.\t | |
