The normal temperature of a human body on centigrade scale is:
Correct answer: C. 37
- A. 98.6
- B. 40
- C. 37
- D. 459.4
Explanation
Option A: A temperature of 98.6 degrees Fahrenheit is equivalent to 37 degrees Celsius. This is the temperature that is often used to measure body temperature in the United States. However, the normal body temperature can vary slightly from person to person. Option B: A temperature of 40 degrees Celsius or higher is considered to be a fever. Option C: The normal temperature of a human body on the centigrade scale is 37 degrees Celsius. The temperature range for a healthy human body is typically between 36.1 and 37.2 degrees Celsius. A temperature of 37 degrees Celsius is considered to be the average normal body temperature. Option D: A temperature of 459.4 degrees Celsius is much higher than the normal body temperature and would be considered to be life-threatening.

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.
