Which of the following statements is NOT correct?
The average kinetic energy of a gas is directly proportional to its temperature
At constant tempearture, the volume of a gas increases as the pressure increases
The pressure of a gas is inversely proportional to its volume
The temperature of a gas is directly proportional to its volume
The collisions of molecules with each other are inelastic
Correct Answer: Option B
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.
