Mercury (Hg) is a metal that melts at –39 oC, and thus is a liquid for temperatures where water is liquid. The latent heat of melting of mercury and specific heat of liquid mercury are: Latent heat of mercury 1.14*10^4 J/Kg and specific heat of mercury is 139J J/kg.
.72 kg of solid mercury at its melting point of –39 oC is placed in thermal contact with 1.15 kg of water, initially at 22 oC, such that they are thermally isolated from everything else.What is the final temperature of the system? Give your answer in oC to at least three digits.
