2.00 kg of water has a volume of 2.00 x 10-3m3 when in the liquid state at 100 °C. When the water is completely changed from liquid to vapour at 100 °C, under a constant atmospheric pressure of1.01 x 105 Pa, the volume increases to 3.38 m3.(i) How much work is done against the atmosphere as the water changes into vapour?(ii) What is the change in the internal energy of the water during vaporization?
