Question

One of the assumptions of the kinetic theory of gases is that there is no force of attraction between the molecules of a gas?

Answer 1

Hint: Kinetic theory of gases is a simple theory which is based on the concept of the real gas states the change in the rate of time of pressure.Kinetic theory has many assumptions which explain about the behavior of gases. Kinetic theory explains about the force of attraction between the gas molecules.

Complete step-by-step answer:
Gases made up of particles which have random motion in the different directions. These particles bounce with the container as well as one another. They deviate from their path when they collide with any other particle and further these processes continue and depend on the sizes of the particles.
Further it is said that here the perfect collision occurs which means that there is no loss of the energy which is not possible for any molecule after getting collided with each other with the system’s wall.
These particles are like point masses so they have no volume. There is no force of attraction or the repulsive force between these particles.
Gas molecules create pressure due to its collision with the container. These collisions are perfectly elastic. No energy lost or gained.
So it is also described that the molecules that have the transformation of the kinetic energy is the heat. It is said that this system comprises the perfect gases which means the real gas with a very high energy and temperature.
Temperature is measured in Kelvin.
All gases have the same average kinetic energy at a given temperature. Light molecules move faster than heavy molecules.

Note: As temperature increases the speed of molecules in gas also increases. Perfectly elastic means no loss or gain of energy. Here are some properties of gases which make them different.
