Answer:

For ideal gas, no effect

Explanation:

Given the following ideal gas relation
(1).............. upload.wikimedia.org
Energy of the molecules is given by
(2) ............ upload.wikimedia.org
setting
(3)............ upload.wikimedia.org, where N is total molecules

Through rearrangement, we can get the following relation

It can be noted from equation (2) that at a particular temperature, there will be one value for energy. This means that the change in mass will be compensated by change in velocity. If the mass increases, velocity will decrease.... and vice versa
