Question

Give the assumptions of the kinetic molecular theory.

Answer 1

Assumption 1

Gases consist of large numbers of tiny particles that are far apart relative to their size.

Assumption 2

Collisions between gas particles and between particles and container walls are elastic collisions (there is no net loss of total kinetic energy).

Assumption 3

Gas particles are continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.

Assumption 4

There are no forces of attraction between gas particles.

Assumption 5

The temperature of a gas depends on the average kinetic energy of the particles of the gas.
