A. -273 K
Explanation:
The minimum average kinetic energy of the molecules in a substance occurs at the temperature of -273K.
This is the lowest of the given temperatures.
- Average kinetic energy of the molecules of substances is directly proportional to their temperature.
- The lower the temperature of a body, the lower their average kinetic energy.
- Increasing temperature leads to more kinetic energy between molecules.
- Since -273K is the lowest temperature, then it shows the minimum average kinetic energy of the molecules.
