1.0 kg of liquid water is boiled at 100^...

1.0 kg of liquid water is boiled at `100^@C` and all of it is converted to steam. If the change of state takes place at the atmospheric pressure `(1.01 xx 10^5 Pa`), calculate
the change in the internal energy of the system. Given , the volume of water changes from `1.0 xx 10^-3 m^3` in liquid form to `1.671m^3` when in the form of steam.
