The world's most active volcanoes, such as the Kilauea volcano in Hawaii, can disgorge about 5 ✕ 105 m3 of 1025°C lava per day. What is the rate of heat transfer out of the earth by convection if this lava has a density of 2523 kg/m3 and eventually cools to 32°C? Assume that the specific heat of lava is the same as that of granite (840 J/(kg · °C)).
The same amount of heat entering identical masses of different substances produces different temperature changes. Calculate the final temperature when 2.05 kcal of heat enters 2.13 kg of the following, originally at 22.2°C. The specific heat capacity for each material is given in square brackets below.
(a) water [1.00 kcal/(kg · °C)] (b) concrete [0.20 kcal/(kg · °C)] (c) steel [0.108 kcal/(kg · °C)](d) mercury [0.0333 kcal/(kg · °C)]
