Neco 2021 Biology Question 19
Practice objective / multiple choice question 19 from the 2021 Neco Biology examination.
At an ambient temperature of 25\,\degree C, a resting adult loses heat by radiation at a rate of 150 kJ·h\(^{-1}\). Heat loss by radiation is proportional to the temperature difference between core body temperature (37\,\degree C) and ambient temperature. (a) Determine the proportionality constant \(k\) (in kJ·h\(^{-1}\)·\degree C\(^{-1}\)). (b) If the ambient temperature drops to 15\,\degree C, calculate the new rate of heat loss. (c) How much additional metabolic heat production (in kJ·h\(^{-1}\)) must be generated by shivering to maintain core temperature?
