Question

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`

Answer 1

Correct Answer - 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`
