What pressure is necessary to change the boiling point of water from its 1.000-atm value of 100°C (373 K) to 97°C (370 K)? The heat of vaporization of water is 40.7 kJ/mol, the density of liquid water at 100°C is 0.958 g/mL and the density of steam is 0.5983 g/L. You will have to use the relationship 101.32 J = 1 L.atm.
