Are you ready for a challenge? Alaska is under 12 kg of sand with a surface area of 1 m2 and a specific heat of 0.84 kJ / (kg-C°). The sun delivers 1.4 kW / m2 but the sand reradiates heat at the rate of 1.3 kW / m2. If the sand's (and Alaska's) initial temperature was 37° Celsius; what will the temperature of the sand be after two hours of baking?
Dessert is waiting, if you get this right!
