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. Then, the final temperature of the gases, Tf in terms of T0 is
(Ignore the heat capacity of boxes)
- \(T_{f}=\frac{3}{7} T_{B}\)
- \(T_{f}=\frac{7}{3} T_{B}\)
- \(T_{f}=\frac{3}{2} T_{B}\)
- \(T_{f}=\frac{5}{2} T_{B}\)
Answer
(C) T_ f = 3 2 T_ B
