The world's deepest gold mine, which is located in South Africa, is
over 5.1 km deep. Every day,
the mine transfers enough energy by heat to the mine's cooling
systems to melt 348114 kg of
ice at 0.0 degrees Celsius. If the energy output from the mine is
increased by 9.6 percent, to what final
temperature will the 348114 kg of ice-cold water be heated?
Latent Heat of fusion of Ice-3.33 × 105 J/kg
Specific heat capacity of Water = 4186J/(kg. °C)
Alligators and other reptiles don’t use enough metabolic energy to keep their body temperatures constant. They cool off at night and must warm up in the sun in the morning. Suppose a 300 kg alligator with an early-morning bodytemperature of 25°C is absorbing radiation from the sun at a rate of 1200 W. How long will the alligator need to warm up to a more favorable 30°C? (Assume that the specific heat of the reptilian body is the same as that of the mammalian body.)
When air is inhaled, it quickly becomes saturated with water vapor as it passes through the moist upper airways. When a person breathes dry air, about 25 mg of water are exhaled with each breath. At 12 breaths/min, what is the rate of energy loss due to evaporation? Express your answer in both watts and Calories per day. At body temperature, the heat of vaporization ofwater is Lv = 24 × 105 J/kg.
