22g of CO(2)" at "27^(@)C is mixed with ...

22g of `CO_(2)" at "27^(@)C` is mixed with `16g" of "O_(2)" at "37^(@)C`. The temperature of mixture is:

A

`27^(@)C`

B

`31.5^(@)C`

C

`32^(@)C`

D

`37^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A
Here `T=(n_(1)T_(1)+n_(2)T_(2))/(n_(1)+n_(2))=((1)/(2)xx300+(1)/(2)xx310)/((1)/(2)+(1)/(2))`
`=150+155=305 K=32^(@)C`
`therefore` Correct choice is (a).
