4.2 Prior to the discovery that freon-12 (CF,CI,).was harmful to the Earth's
ozone layer, it was frequently used as the dispersing agent in spray cans for
hair spray, etc. Its enthalpy of vaporization at its normal boiling point of
-29.2°C is 20.25 kJ mol. Estimate the pressure that a can of hair spray using
freon-12 had to withstand at 40°C, the temperature of a can that has been
standing in sunlight. Assume that AH is a constant over the temperature
range involved and equal to its value at-29.2°C.
