Two rigid boxes containing different ideal gases are placed on a table. Box 
contains one mole of nitrogen at temperature 
, while Box 
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 terms of 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
When two gases are mixed together, then Heat lost by the helium gas 
Heat gained by the nitrogen gas
