The Kilauea volcano in Hawaii is the world’s most active, disgorging about 5×10^5m3 of 1200ºC lava per day. What is the rate of heat transfer out of Earth by convection if this lava has a density of 2700kg/m3 and eventually cools to 30ºC ? Assume that the specific heat of lava is the same as that of granite.
