Question

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 300kg alligator with an early-morning body temperature of 25C is absorbing radiation from the sun at a rate of 200 . How long will the alligator need to warm up to a more favorable 30C ? (Assume that the specific heat of the reptilian body is the same as that of the mammalian body.) Express your answer to three significant figures and include the appropriate units.
