Absolute zero is equivalent to:
Correct answer: D. All of these
- A. 0K
- B. -273.15 C
- C. -459.4 F
- D. All of these
Explanation
Absolute zero is one temperature written on three scales: 0 K, -273.15 C and about -459.67 F. Each describes the point at which molecular kinetic energy reaches its minimum, so all of these are correct.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
