How do u do these problems? send work. Transcribed Image Text: 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 1.60 mt of the metal is
cooled from room temperature (23.0°C) to -38.8°C and then frozen to a solid? (The density of mercury is 13.6 g/cm. Its specific heat is 0.140 3/g*K and its heat of fusion is 11.4 /g.)
Chloromethane, CH,CI, is used as a topical anesthetic. The temperature at which CH,CI liquid turns into a vapor (the boiling point) is 24.09°C. What quantity of heat must be absorbed
by the liquid to convert 170. g of liquid to a vapor at 24.09 C? The heat of vaporization of CH,Ci is 21.40 k/mol.
