(a) How much work is done on the steam when 3.81 mol of water at 100C boils and becomes 3.81 mol of steam at 100C at 1.00 atm pressure? (Assume the latent heat of vaporization of water is 2.26 X 10 J/kg.) Bs) (b) Assume the steam to behave as an ideal gas. Determine the change in internal energy of the system of the water and steam as the water vaporizes. [ o Need Help? Submit
