Question

2.0 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 x 10³ Pa), calculate 
i.the energy transferred to the system,
ii.the work done by the system during this change, and
iii.the change in the internal energy of the system. Given, the volume of 2 kg of water changes
from 2.0 x 10³ m² in liquid form to 3.342 m' when in the form of steam.
