Hello, So, I am reading this theory, and I come across this sentence explaining to me that gas particles of different mass have the same average kinetic energy at a particular temperature. Is this somehow due to momentum? Each particle is given a certain energy which will cause them to move at a certain velocity, and, since they have different masses, the energy they receive will cause them to move at a certain velocity that is relative to their mass? If this isn't a correct way of thinking, please explain to me why particles of different masses can have the same average kinetic energy. Thank you.
