Question

What are the major assumptions that separate an ideal gas from a real gas?

Answer 1

The major assumptions that separate an ideal gas from real gases are ---

1) Ideal gas does not have definite volume whereas a real gas has a definite volume.

2) Ideal gas does not have any mass whereas a real gas has mass.

3) In ideal gas, the collision between the particles is elastic. On the otherhand, the collision between the particles in real gas is non-elastic.

4) During collision, no energy is involved between particles in ideal gas whereas the collision between particles in real gases has attractive energy.

5) In ideal gas, the pressure is high as compared to real gas.

6) The equation PV = nRT is followed by ideal gas. But the real gas follows the equation ( P + a / v²) ( v-b) = RT
