Normal human body temperature 98.6°F corresponds to______________?
Correct answer: A. 37°C
- A. 37°C
- B. 42°C
- C. 55°C
- D. 410°C
Explanation
Convert using C = (5/9)(F - 32): C = (5/9)(98.6°F - 32°F) = (5/9)(66.6°F) = 37°C. Thus normal body temperature is approximately 37°C. A student may choose 42°C by recalling that body temperature is near 100°F but applying an incorrect conversion.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
