Neco 2022 Biology Question 27
Practice objective / multiple choice question 27 from the 2022 Neco Biology examination.
A person's normal body temperature is \(37^{\circ}\text{C}\). After five minutes of vigorous exercise the temperature rises to \(39.5^{\circ}\text{C}\). When exercise stops, the body cools according to Newton's law of cooling: \(T(t)=T_{\text{env}}+(T_{0}-T_{\text{env}})e^{-kt}\). The ambient temperature is \(25^{\circ}\text{C}\). Ten minutes after stopping, the measured temperature is \(38.0^{\circ}\text{C}\). (a) Determine the cooling constant \(k\) (in min\^{-1}). (b) Using this \(k\), calculate how long it will take for the temperature to fall to \(37.5^{\circ}\text{C}\).
