An average human produces about 10 MJ of heat each day through metabolic activity. If a human body were an isolated system of mass 80 kg with the heat capacity of water, what temperature rise would the body experience? Heat capacity of water = 4.2 J/K-g.
Options:
Answer:
A
Solution:
Heat capacity of the body = 80000 g × 4.2 = 3.36×105 J/K. Δ T = 10×106 / 3.36×105 = 29.76 K, which is a rise of 29.76°C. Matches (a).
