Homework Statement
The world's most active volcanos, such as the Kilauea volcano in Hawaii, can disgorge about 5 ✕ 105 m3 of 1000°C lava per day. What is the rate of heat transfer out of the Earth by convection if this lava has a density of 2800 kg/m3 and eventually cools to 32°C? Assume that the specific heat of lava is the same as that of granite. Answer in MW.
Homework Equations
D=m/v
Q=mc(tf-ti)
