State three postulates of the kinetic molecular theory of gases.
Original Khojo Papers practice question — not from a past board paper.
Answer
A gas consists of a very large number of tiny particles in constant, rapid, random motion. The volume of the particles themselves is negligible compared with the volume of the container, and the forces between them are negligible. Collisions between particles and with the walls are perfectly elastic, and the pressure of the gas arises from these collisions.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The average kinetic energy of the particles is proportional to the absolute temperature.
