The scenario: You have two cups of water at temperatures Th and Tc (in Celcius), each of which contains the same mass, m (in kg) of water. When you put them in a freezer, a mass (m, in kg) immediately evaporates off the hot water. Ignore evaporation from the cold water. The specific heat of liquid water is c (in kJ/kg/C), the specific latent heat of vaporization of water is Lv (in kJ/kg), and the specific latent heat of fusion of water is Lf (in kJ/kg). Write a symbolic expression for QC, the amount of heat (in kJ) that must be removed from the cold water in order to lower its temperature to 0°C, and then freeze it. Your expression will involve the variables m, c, Tc, and Lf

After the sinking of RMS Titanic, US operated the International Ice patrolwith the purpose of monitoring the presence and movements of icebergsin the Atlantic and Arctic oceans. Once, they observed a unique tabulariceberg in a form of a rectangle (250 km x 50 km x 300 m). How manyyears would it take to melt the iceberg solely by heat from the sun if theice absorbs a mean of 98 J/m2-s, 12.5 hrs per day?
