A resting adult produces metabolic heat at a rate of \(100\ \text{W}\). In a hot environment the person sweats at a rate of \(0.5\ \text{g min}^{-1}\). The latent heat of evaporation of water is \(2.43\ \text{kJ g}^{-1}\). The specific heat capacity of the human body is approximately \(350\ \text{kJ \degree C}^{-1}\). Assuming all evaporated sweat removes heat, calculate the rise in core body temperature after one minute.
