Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at temperature T o , while box B contains one mole of helium at temperature (7/3) T o . 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, T f in terms of T 0 is:
A
B
C
