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//2`

C

`1//4`

D

`1//8`

Text Solution

Verified by Experts

The correct Answer is:
C
Here P does not change
`(V_(1))/(V_(2)) = (T_(1))/(T_(2))`
`(v)/(V_(2)) = (300)/(400)`
`V_(2) = (4)/(3)v`
`:.` Amount of gas escaped
`= V_(2) - V_(1) = (v)/(4)`
thus `1//4` of the original volume of the gas will escape
