Metabolism is the name of a process in which energy transformation takes place within______________?
Correct answer: B. Human body
- A. Heat engine
- B. Human body
- C. Atmosphere
- D. Laboratory
Explanation
Metabolism is the set of chemical reactions in a living organism through which nutrients are converted into usable energy and other substances. Therefore, the energy transformation occurs within the human body. The likely distractor is a, because a heat engine also transforms energy, but metabolism is specifically a biological process.

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.
