The Kilauea volcano in Hawaii is the world’s most active, disgorging about 5 X 105 m3 of 1200C lava per day. What is the rate of heat transfer out of Earth by convection if this lava has a density of 2700 kg/m3 and eventually cools to 30C? Assume that the specific heat of lava is the same as that of granite.
