Best Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):est Answer: Change of internal energy equals heat transferred to plus work done on the gas, i.e.: âU = Q + W = 300kJ - 350kJ = -50kJ. Source(s):
Energy expenditure is mainly a sum of internal heat produced and external work. The internal heat produced is, in turn, mainly a sum of basal metabolic rate (BMR) and the thermic effect of food. External work may be estimated by measuring the physical activity level (PAL).
