Mass of 1 = 
Mass of 2 = 
Temperature in 1 = 
Temperature in 2 = 
Pressure remains i the group apartment
The closed system and energy balance is
The kinetic energy and potential energy are negligible
since it is insulated tank ,there wont be eat transfer from the system
And there is no work involved
Let the final temperature be final temperature
Using mass balance
from eqn i
Therefore the final temperature can be express as
