Question

Which of the following is not true according to Kinetic Theory of Gases ?

• A. Ratio of volume of the gas to volume occupied by the molecules is negligible.
• B. Molecules are in continuous motion.
• C. Molecules have kinetic energy.
• D. The system of molecules, either gains or looses energy during collisions.

Answer 1

The correct option is D The system of molecules, either gains or looses energy during collisions.

According to the assumptions of KTG, the collision of gas molecules are perfectly elastic. So, kinetic energy is conserved.
Hence, option (d) is not true.
