The translational kinetic energy of the molecules of a gas at absolute temperature (T) can be doubled (a) by increasing T to 4T (b) by increasing T to 2T (c) by decreasing T to T/2 (d) by increasing T to √(2)T

Answer: (b). Translational KE = 3/2kBT, so KE ∝ T. Doubling the KE needs T → 2T. So the answer is (b) by increasing T to 2T.
