Question

The kinetic theory of matter helped a great deal in understanding the behaviour of gases. Which of the following statements did not belong to it?

• A. When the gas is heated by raising its temperature the molecules move faster
• B. The molecules in a gas are always moving
• C. Gases are made up of small particles called molecules
• D. When molecules collide, they lose energy

Answer 1

The correct option is D When molecules collide, they lose energy

When molecules collide, they lose energy.

The kinetic theory states that, no energy is gained or lost when molecules collide.

Hence, statement D does not belongs to the kinetic theory of gas.
