Total K.E of a sample of a gas which contain `1times10^(22)` molecules is 500 cal at `-73^(0)C` .Another sample of a gas at `127^(@)C` has a total kinetic energy of 1500 cals.Then the number of molecules in the second sample of gas is

A sample of gas contains N_(1) molecules and the total kinetic energy at -123^(@)C is E_1 ergs. Another sample of gas at 27^@C has total kinetic energy as 2E_(1) ergs. Assuming gases to be ideal, the number of gas molecules in the second sample will be

The kinetic energy of N molecules of O_(2) is x joule at -123^(@)C . Another sample of O_(2) at 27^(@) C has a kinetic energy of 2x. The latter sample contains molecules of O_(2) .

The KE of N molecule of O_(2) is x joules at -123^(@)C . Another sample of O_(2) at 27^(@)C has a KE of 2x joules. The latter sample contains

Total kinetic energy of molecules of a gas sample varies K.E.=(7)/(4)nRT . This sample contains
