What quantity of heat energy must be released


The freezing point of mercury is -38.8°C, is the only metal that is liquid at room temperature. What quantity of heat energy,in joules, must be released by mercury if 1.20 mL of mercury is cooled from 23.0°C to-38.8°C and then frozen to a solid? (The density of liquidmercury is 13.6 g/cm3. Its specific heat capacity is0.140 J/g·K and its heat of fusion is 11.4J/g.)
