Question

What are the postulates of kinetic theory

Answer 1

*Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion.

*These particles move in a straight line until they collide with another particle or the walls of the container.

*These particles are much smaller than the distance between particles. Most of the volume of a gas is therefore empty space.

*There is no force of attraction between gas particles or between the particles and the walls of the container.

*Collisions between gas particles or collisions with the walls of the container are perfectly elastic. None of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.

*The average kinetic energy of a collection of gas particles depends on the temperature of the gas and nothing else.

Answer 2

Answer:

The kinetic-molecular theory of gases can be stated as four postulates: A gas consists of molecules in constant random motion. Gas molecules influence each other only by collision; they exert no other forces on each other. All collisions between gas molecules are perfectly elastic; all kinetic energy is conserved.
