Question:

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

Decrease in its pressure

Increase in its kinetic energy

Decrease in intermolecular distance

Increase in its mass

Solution:

Correct option is B. Increase in its kinetic energy. Increase in temperature would lead to the increase in kinetic energy of gas (assuming gas to be ideal) as U = (3/2)nRT. Hence option B is correct answer.
