Question

at 25°c the heat of fusion of aluminum is 10.6 kj/mol and the heat of sublimation is 326.4 kj/mol. what is the heat of vaporization of aluminum at 25°c?

Answer 1

The heat of vaporization of aluminium at 25 °C is 315.8 kilojoules per mole.

The sublimation is the phase change of a substance from solid to gas, the fusion is the phase change of a substance from solid to liquid and the vaporization is the phase change of a substance from liquid to gas. The heat of vaporization is the difference between the heat of sublimation and the heat of fusion, that is to say:

$h_{v} = 326.4\,\frac{kJ}{mol}-10.6\,\frac{kJ}{mol}$

$h_{v} = 315.8\,\frac{kJ}{mol}$

The heat of vaporization of aluminium at 25 °C is 315.8 kilojoules per mole.
