The scales of temperature are based on two fixed points, which are
Correct answer: B. The temperature of melting ice and boiling water at atmospheric pressure
- A. The temperatures of water at 0°C and 100°C
- B. The temperature of melting ice and boiling water at atmospheric pressure
- C. The temperatures of ice cold and boiling water
- D. The temperatures of frozen and boiling mercury
Explanation
The temperature of melting ice and boiling water at atmospheric pressure are 0°C and 100°C respectively.

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.
