Example 4.3 : 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 x105 Pa), calculate (a) the energy transferred to thesystem, (b) the work done by the system during this change, and (c) the change in the internal energy of the system. Given, the volume of water changes from 1.0 x 103 m' in liquid form to 1.671 m3 when in the form of steam
