Question

Two vessels of the same volume contain the same gas at same temperature. If the pressure in the vessels be in the ratio of 1 : 2, then

  1. the ratio of the average kinetic energy is 1 : 2    
  2. the ratio of the root mean square velocity is 1 : 1    
  3. the ratio of the average velocity is 1 : 2    
  4. the ratio of number of molecules is 1 : 2    

The correct answer is: the ratio of the root mean square velocity is 1 : 1
