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

Options

  1. Aincreasing T to 4 T
  2. Bincreasing T to 2 T
  3. Cdecreasing T to T/2
  4. Dincreasing T to 2T

Correct answer

D. increasing T to 2T

Step-by-step solution

The translational kinetic energy of the molecules of a gas is given by E = 3 2 k_B T . Since E T , to double the translational kinetic energy, the absolute temperature must be doubled. Therefore, the temperature should be increased to 2T . Answer: increasing T to 2T
