• The size of the molecules should be infinitely small
• The gas should occupy 22.4 L of volume for every mole at STP
• There should be a strong force of attraction between the gas molecules
• Helium is the only gas that can be considered an ideal or perfect gas due to its small molecular weight

Answers:

1. 1. True

• The gas particles are point masses having infinitely small sizes with no volume.
• All the collisions are elastic. No energy is gained or lost during the collision.
• All gases at a given temperature have the same average kinetic energy.
• Follow all the 3 gas laws perfectly
