Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at temperature T0, 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, what will be the final temperature of the gases, Tf, in terms of T0?

Two thermally insulated vessels 1 and 2 are filled with air at temperatures (T1, T2 ), volume (V1, V2 ), and pressure (P1, P2 ), respectively. If the valve joining the two vessels is opened, the temperature inside the vessel at equilibrium will be

An insulated container of gas has two chambers separated by an insulating partition. One of the chambers has volume V1 and contains ideal gas at pressure P1 and temperature T1. The other chamber has volume V2 and contains ideal gas at pressure P2 and temperature T2. If the partition is removed without doing any work on the gas, the final equilibrium temperature of the gas in the container will be
