Question

Which of the following statement is not a postulate of kinetic molecular theory of gases?

• A. $K.E.$ is dependent on temperature
• B. $K.E.$ is dependent on pressure
• C. The molecular collisions are perfectly elastic collisions
• D. The pressure of the gas is due to collisions of gas molecules on the walls of the vessel

Answer 1

The correct option is B $K.E.$ is dependent on pressure

Pressure does not have any effect on the kinetic energy of the molecule. Gas pressure is due to the molecules colliding to the walls of the container. the kinetic energy of the molecule directly proportional to the temperature.
