Gce Model Questions Vol1 2021 Biology Question 6
Practice objective / multiple choice question 6 from the 2021 Gce Model Questions Vol1 Biology examination.
During exposure to a hot environment (ambient temperature \(30^{\circ}\text{C}\)), a person with a core temperature of \(37^{\circ}\text{C}\) generates metabolic heat at a rate of \(100\ \text{W}\). Heat is lost by convection, modelled as \(Q_{\text{conv}} = hA(T_{\text{body}}-T_{\text{env}})\) with \(hA = 10\ \text{W}\,^{\circ}\text{C}^{-1}\), and by evaporation of sweat at a rate of \(0.5\ \text{g min}^{-1}\). The latent heat of vapourisation of water is \(2.43\ \text{MJ kg}^{-1}\). Will the person's core temperature increase, decrease, or remain constant? State the expected direction.
