The latent heat of vaporisation of water...

The latent heat of vaporisation of water is 2240 J/gm. If the work done in the process of expansion of 1 g of water is 168 J, then increase in internal energy is

2408 J

2240 J

2072 J

1904 J

Text Solution

Verified by Experts

The correct Answer is:

`DeltaQ=mL=1xx2240=2240J`
`DeltaW=168J`
`DeltaU=DeltaQ-DeltaW=2240-168=2072J`
