[KT4 6.031.] Mercury, with a freezing point of -38.8�C, is the only metal that is liquid at room temperature. How much heat energy (in joules) must be released by mercury if 1.20 mL of the metal is cooled from room temperature (22.0�C) to -38.8�C and then frozen to a solid? (The density of mercury is 13.6 g/cm3. Its specific heat is 0.140 J/g � K and its heat of fusion is 11.4 J/g.)
