Question

A gas in an open container is heated from `27^(@)C` to `127^(@)C` The fraction of the original amount of gas remaining in the container will be .
A. `3//4`
B. `1//2`
C. `1//4`
D. `1//8`

Answer 1

`P_(1)V_(1)=n_(1)RT_(1)`
`P_(2)V_(2)=n_(2)RT_(2)`
`(n_(2))/(n_(1))=(T_(1))/(T_(2))=(300)/(400)=(3)/(4)`
`n_(2)=(3)/(4)n_(1)`
Escaped`=(1)/(4)`
