Ideal Gas Assumptions

A list of the assumptions made for ideal gases in IB Physics

Molecule size

Point particles with negligible volume

Molecule obedience

Obey the laws of mechanics

Molecule forces

No forces except during collisions

Collision time

Time during a collision is negligible compared to time between collisions

Collision nature

Collisions between particles and container walls are elastic

Molecule movement

Molecules have a range of speeds and move randomly
