Pressure & Kinetic Energy of a Gas

The translational kinetic energy of the molecules of a gas at absolute temperature (T) can be doubled

Show answer and solution

Answer: (b)

  1. Translational KE =32kBT= \frac{3}{2}k_BT, so KE ∝T\propto T.
  2. Doubling the KE needs T→2TT \to 2T.
  3. So the answer is (b) by increasing TT to 2T2T.
