Thermodynamics Question 331
Question: Two rigid boxes containing different ideal gases are placed on a table. Box A contains one mole of nitrogen at temperature While Box B contains one mole of helium at temperature (7/3) . 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, in term of is
Options:

C)
D)
Show Answer
Answer:
Correct Answer: B
Solution:
[b] When two gases are mixed together then Heat lost by the Helium gas = Heat gained by the Nitrogen gas
By solving we get
