the gases contain 10^22 and 10^23 molecules present in different vessels at the same temperature. the ratio of their average K.E is

the correct answer is 1:1 i think please give explanation

Hmmm. Same volume for the different vessels, that matters...

Asumming same volume, then the pressures must be different. However, temperature is a measure of avg KE, so if they are at same temperature, then they must have the same avg KE.
