The world's most active volcanoes, such as the Kilauea volcano in Hawaii, can disgorge about 5.00 X 105 m3 of 1100°C lava
per day. What is the rate of heat transfer (in MW) out of the earth by convection, if this lava has a density of 2800 kg/m3 and
eventually cools to 25°C? Assume that the specific heat of lava is the same as that of granite.

The exterior walls of a house have a total area of 194 m2 and are at 12.4°C and the surrounding air is at 7.4° C. Find the rate of convective cooling of the walls, assuming a convection coefficient of 2.9 W/(m2·°C). Since you're looking for the rate of cooling, your answer should be entered as positive.
Suppose you want to raise the temperature of a 0.18-kg piece of ice from -20.0°C to 130°C. The heat of fusion is Lf = 334 kJ/kg, and the heat of vaporization is Lv = 2256 kJ/kg. In this problem, take 1520 J/kg⋅°C as the specific heat of steam, and 2090 J/kg⋅°C as the specific heat of ice. a.) How much heat, in kilocalories, must be transferred for this to happen, including the energy needed for phase changes? b.) How much time, in seconds, is required to do this, assuming a constant 20.0 kJ/s rate of heat transfer?
