A sample of oxygen gas expands its volume from `3L` to `5L` against a constant pressure of `3` atm. If work done during expansion be used to heat `10 ` mole of water initially present at `290K` , its finally temperature will be `(` specific heat capacity of water `=4.18 J//k-g) :`

`292.0K`

`298.0K`

`290.8K`

`293.7K`

Text Solution

Verified by Experts

The correct Answer is:

`P(V_(2)-V_(1))=mSDeltaT`
`3(2)xx101.3=180xx4.18xx(T_(f)-290)`
`T_(f)=290.8K`
