Figure 8.26

Postby Lisa Tang 1C » Tue Jan 09, 2018 10:38 pm

In the description that accompanies the heating curve in Figure 8.26, it states that "the heating curve for the liquid is not as steep as for the solid because the liquid has the higher heat capacity." Is this the general trend (that liquids tend to have higher heat capacities than solids of the same substance) or is this only because of the strong intermolecular forces that exist between liquid water molecules?

This is an exception because of water's special properties. Usually, the heat capacity of solids is greater than that of liquids, so the slope for the transition from solid to liquid is more gradual/less steep than the slope for the transition from liquid to gas.
