Q1. a) Using steam tables, calculate the work done against the environment when 1 kg of water at 1 atm and 100C is evaporated to steam at the same temperature and pressure. b) Repeat part a) assuming that steam is an ideal gas. c) Using steam tables, calculate the heat needed to perform the evaporation. d) What thermodynamic function represents the difference between heat added and work performed? Look up its value in the steam tables. e) Using steam tables, calculate the change in Gibbs Free Energy (AG) during the evaporation. What value would you expect, and why? )
