Fig. 1.3 The change in temperature of one mole of H2O vs amount of heat, at a pressure of 1 atm. At the
melting point, absorption of heat does not change the temperature until all the ice melts. It takes about 6
kJ to melt 1 mole of ice, the "latent heat" discovered by Joseph Black. Then the temperature increases
until the boiling point is reached, at which point it remains constant till all the water turns to steam. It
takes about 40 kJ to convert 1 mole of water to steam.
