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

A

`292.0K`

B

`298.0K`

C

`290.8K`

D

`293.7K`

Text Solution

Verified by Experts

The correct Answer is:
C
`P(V_(2)-V_(1))=mSDeltaT`
`3(2)xx101.3=180xx4.18xx(T_(f)-290)`
`T_(f)=290.8K`
