These are 3 assumptions that i know for a fact. Hope this helped.
1.Gas particles are continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.
2.There are no forces of attraction between gas particles.
3.The temperature of a gas depends on the average kinetic energy of the particles of the gas.
