A cup of water with a temperature of 95C is placed in aroom with a constant temperature
Chapter 8, Problem 59(choose chapter or problem)
A cup of water with a temperature of \(95^{\circ} \mathrm{C}\) is placed in a room with a constant temperature of \(21^{\circ} \mathrm{C}\).
(a) Assuming that Newton's Law of Cooling applies, use the result of Exercise 58 to find the temperature of the water t minutes after it is placed in the room. [Note: The solution will involve a constant of proportionality.]
(b) How many minutes will it take for the water to reach a temperature of \(51^{\circ} \mathrm{C}\) if it cools to \(85^{\circ} \mathrm{C}\) in 1 minute?
