Question

The world's most active volcanoes, such as the Kilauea volcano in Hawaii, can disgorge about 5.00 ✕ 105 m3 of 1400°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 2600 kg/m3 and eventually cools to 30°C? Assume that the specific heat of lava is the same as that of granite.

________MW
