Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at a temperature To, while box B contains one mole of helium at temperature (7/3) $$T0$$. The boxes are then put into thermal contact with each other and heat flows between them until the gases reach a common final temperature (Ignore$$ the heat capacity of $$boxes). Then the final temperature of the gases, Tf, in terms of $$T0$$ is :

Question

Infinity Learn · Accepted Answer

Let final temperature be Tf $$thenTf=n1C$$ $$V1T1+n2CV2T2n1CV1+n2CV2=(1)52R(T0)+(1)32R73T0(1)52R+(1)32R=32T0$$
