Two gases A and B are at absolute temperatures 360 ~K and 420 ~K respectively. The ratio of average kinetic energy of the molecules of gas B to that of gas A is

Options

  1. A6: 7
  2. B7 : 6
  3. C7: 6
  4. D49: 36

Correct answer

C. 7: 6

Step-by-step solution

The mean kinetic energy 1 2 ~m ^2 of the gas molecule is proportional to the temperature T . K _ B K _ A = T _ B T _ A = 420 360 = 7 6
