If a system absorbs heat, the surrounding temperature:
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains Same
- D. Decreases then suddenly increases
Explanation
When a system absorbs heat from its surroundings, it gains thermal energy. According to the first law of thermodynamics, which is the law of conservation of energy, the heat absorbed by the system is equal to the increase in its internal energy. As the system gains internal energy, the temperature of the system increases. Therefore, the correct option is that the surrounding temperature increases.

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.
