Question

Which of the following statements is NOT correct?

Options

A) The average kinetic energy of a gas is directly proportional to its temperature

B) At constant tempearture, the volume of a gas increases as the pressure increases

C) The pressure of a gas is inversely proportional to its volume

D) The temperature of a gas is directly proportional to its volume

E) The collisions of molecules with each other are inelastic


The correct answer is B.

Explanation:

Increasing the pressure confines the gas molecules to a smaller space, thereby reducing the volume. Reducing the pressure the other way round increases the volume of a gas.
