According to Newtons law of cooling, the temperature T of a body at time t is given by T
Chapter 3, Problem 11(choose chapter or problem)
According to Newton's law of cooling, the temperature of a body at time is given by \(T=T_{a}+\left(T_{o}-T_{a}\right) e^{-k t}\), where \(T_{a}\) is the ambient temperature, \(T_{0}\) is the initial temperature, and is the cooling rate constant. For a certain type of beverage container, the value of is known to be 0.025 \mathrm{~min}^{-1}\)
a. Assume that \(T_{a}=36^{\circ} \mathrm{F}\) exactly and that \(T_{0}=72.0 \pm 0.5^{\circ} \mathrm{F}\). Estimate the temperature at time \(t=10 \mathrm{~min}\), and find the uncertainty in the estimate.
b. Assume that \(T_{o}=72^{\circ} \mathrm{F}\) exactly and that \(T_{a}=36.0 \pm 0.5^{\circ} \mathrm{F}\). Estimate the temperature at time \(t=10 \mathrm{~min}\), and find the uncertainty in the estimate.
