A gas in an open container is heated from `27^(@)C` to `127^(@)C`. The fraction of the original amount of the gas remaining in the container will be

A

`3//4`

B

`1//4`

C

`2//3`

D

`1//8`

Text Solution

Verified by Experts

The correct Answer is:
B
`(V_(1))/(T_(1)) = (V_(2))/(T_(2))` initial fraction `(V_(1))/(V_(2)) = 1` when temp. is `27^(@)C`
At `127^(@)C`, the new fraction is `(V_(1))/(V_(2)) = (300)/(400) = (3)/(4)`
`:.` Air expelled `= 1 - (3)/(4) = (1)/(4)`
