Does the average K.E. per molecule of the gas depend upon the mass of the molecule ?

Does the value of 'g' depend upon mass of the body?

At what temperature will the average KE per molecule of a gas be exactly half its value at NTP?

The position of centre of mass does not depend upon the reference frame. Centre of mass depends only upon the mass of the body.

On which factors does the average KE of gas molecules depend : nature of gas, its temperature , its volume?

The shape of a molecule depends upon___

How is the average KE of a gas molecule related to the temperature of the gas ?

How many collisions per second does each molecule of a gas make, when average speed of the molecule is 500m//s and mean free path is 2.66 xx 10^(-7) m ?

If the average kinetic energy of a molecule of hydrogen gas at 300 K is E , then the average kinetic energy of a molecule of nitrogen gas at the same temperature is

Each molecule of nitrogen gas heated in a vessel to a temperature of 5000K has an average energy E_(1) . Some molecule of the gas escape into atmosphere at 300K. Due to collision with air molecules, average kinetic energy of the nitrogen molecule changes to E_(2) . Find the radio E_(1)//E_(2) .
