###### Newton's Law of Cooling A thermometer reading $72^{\circ} \mathrm{F}$ is placed in a refrigerator where the temperature is a constant $38^{\circ} \mathrm{F}$ (a) If the thermometer reads $60^{\circ} \mathrm{F}$ after 2 minutes, what will it read after 7 minutes? (b) How long will it take before the thermometer reads $39^{\circ} \mathrm{F} ?$ (c) Determine the time that must elapse before the thermometer reads $45^{\circ} \mathrm{F}$. (d) What do you notice about the temperature as time pass
