3/30/2013 Heats of Fusion and Solidification◦ How does the quantity of heat absorbed by amelting solid compare to the quantity of heatreleased when the liquid solidifies?• The heat of fusion (H f ) is the heat absorbed by onegram of a solid substance as it melts to a liquid at aconstant temperature.• The heat of solidification (H s ) is the heat lost when onemole of a liquid solidifies at a constant temperature.• For water:H f = 334 J/gReference table B19
