According to Newton's law of cooling, the rate at which a substance cools in alir is directly proportional to the difference between the temperatures of the substance and that of air. If the temperature of the air is 30° and the substance cools from 100* to 70* in 15 minutes, how long will it take to cool 100* to 50? a. 33. 59 min C. 41.74 min d. 45.90 min b. 43.80 min
