Question
22 g of carbon dioxide at 27
is mixed in a closed container with 16 g of oxygen at 37
. If both gases are considered as ideal gases, then the temperature of the mixture is
- 24.2
- 28.5
- 31.5
- 33.5
The correct answer is: 31.5
For carbon dioxide, number of moles 
molar specific heat of
at constant volume 
For oxygen, number of moles 
molar specific heat of
at constant volume 
Let
be the temperature of mixture.
Heat lost by
= Heat gained by
