The work done by the system in the conversion of `1 mol` of water at `100 ^(@)C` and `760` torr to steam is `-3.1 kJ`. Calculate the `DeltaE` for the conversion (Latent heat of vaporisation of water is `40.65 kJ mol^(-1)`)
A. `43.75 kJ`
B. `101.35 kJ`
C. `37.55 kJ`
D. `-40.65 kJ`

Correct Answer - C
According to first law,
`DeltaE=q+W`
`:. DeltaE=40.65-3.1=37.55 kJ`
