Topic: Kinetic interpretation of temperature, RMS speed· Kinetic Theory of Gases

Increase in temperature of a gas filled in a container would lead to :

1. increase in its mass

2. increase in its kinetic energy

3. decrease in its pressure

4. decrease in intermolecular distance

Answer: 2. increase in its kinetic energy

The temperature of a gas measures the average kinetic energy of its molecules. Raising the temperature raises the kinetic energy.

Mass does not change with temperature. Pressure would increase (at constant volume) rather than decrease. The molecules in a rigid container do not move closer, so option 4 is wrong too.
