To expel half the mass of air from a large flask at `27^(@)C` it must be heated to .

A

`54^(@)C`

B

`177^(@)C`

C

`277^(@)C`

D

`327^(@)C`

Text Solution

Verified by Experts

`PV =nRT ` at constant `P` and `V`
`n_(1) T_(1) =n_(2) T_(2)`
`n_(1) xx 300 = (n_(1))/(2) xx T`
`:. T = 600 K =327^(@)C` .
