5. If molten metal is dropped quickly onto a highly chilled surface it is possible that the metal may become supercooled (i.e., the temperature may fall below the melting temperature) before it solidifies. Imagine that this happens to liquid cadmium (Cd), for which Tm=594 K and ΔHm=6401.5 J/mole. It may (or may not) be useful for you to also know that Cp(s) = 22.217 and Cp(l) = 29.706 J/mol⋅K.

a. If it solidifies isothermally at 55 K below the equilibrium (normal) melting point of Cd, what is magnitude of the energy transferred to the plate?

b. Is the energy greater or less than if the Cd had solidified at the equilibrium temperature?
