if you mix different amounts of two ideal gases that are originally at differnt temperaures what must be true of the final state after the temprature stabilizes ( There may be more than one correct choice)
A) both Gases wil reach the same final temperature
B) the final rms molecular speed will be the same for both gases
c) the final average kinetic energy of a molecular will be the same for both gases

Since the temperature stabilizes, that means the gaseous mixture hit equilibrium, and there was a heat exchange between the gases that caused the temperatures to be equal to each other. 

We know that temperature is also equal to the average kinetic energy, so since the gases have the same final temperature, we also know they have the same average kinetic energy.

So I think the answer would be A and C.
