BIO Before going in for his annual physical, a 70.0-kg man whose body temperature is 37.0o C consumes an entire 0.355-L can of a soft drink (mostly water) at 12.0o C. (a) What will his body temperature be after equilibrium is attained? Ignore any heating by the man’s metabolism. The specific heat of the man’s body is 3480 J/kg ? K. (b) Is the change in his body temperature great enough to be measured by a medical thermometer?
ANSWER:ANSWER: a) The mass of the man is 70 kg. The specific heat of his body is 3480 Jules / kg . K . He drank 0.355 L of soft drink whose mass is 0.355 kg. The specific heat of water is 4184 J/kg.K The body temperature of the man before drinking the soft drink was 0 37 C = 236.15 K 0 The temperature of the soft drink was 12 C = 261.15 K . As we know the heat lost by the
