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

A

2408 J

B

2240.J

C

2072 J

D

1904 J

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta Q=Delta U+Delta W implies Delta U=Delta Q-Delta W=2240-168=2072 J`.
