The heat of vaporization of water at atmospheric pressure is Lv = 2260 kJ/kg.  a. How much of this heat represents work done to expand the water into steam against the  pressure of the atmosphere?  b. What becomes of the rest of the heat? At T = 1000C and p = 1.00 atm, the density of water  is 1.00 x 10 3 kg/m3 and the density of steam is 0.600 kg/m3

The heat of vaporization of water at atmospheric pressure is Lv = 2260 kJ/kg.

 a. How much of this heat represents work done to expand the water into steam against the

 pressure of the atmosphere?

 b. What becomes of the rest of the heat? At T = 1000C and p = 1.00 atm, the density of water

 is 1.00 x 10 3

kg/m3

and the density of steam is 0.600 kg/m3
