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 and heat exchange will happen only between boxes ) . Then the final temperature of the gases in terms of 𝑇_𝑜 is 7/3 𝑇_𝑜 3/2 𝑇_𝑜 5/2 𝑇_𝑜 3/7 𝑇_𝑜
