Air open vessel at `127^(@)C` is heated until `1//5^(th)` of air in it has been expelled. Assuming that the volume of vessel remains constant the temperature to which the vessel has been heated is

A

`177^(@)C`

B

`277^(@)C`

C

`377^(@)C`

D

`477^(@)C`

Text Solution

Verified by Experts

The correct Answer is:

D

Under similar conditions
`n_(1)T_(1)=n_(2)T_(2)`
`n_(1)xx600=(4)/(5)n_(1)xxT_(2)`
`T_(2)= 750 K`
`T_(2)= 477^(@)C`
