In most temperature scales, 0 does not universally mean "no temperature." The interpretation of 0 depends on the temperature scale being used:
1. **Celsius (°C)**: In the Celsius scale, 0°C is the freezing point of water, not the absence of temperature. Absolute zero, the point at which molecular motion stops, is -273.15°C.
2. **Fahrenheit (°F)**: In the Fahrenheit scale, 0°F is a specific point on the scale, not related to the absence of temperature. It is equivalent to -17.78°C.
3. **Kelvin (K)**: In the Kelvin scale, 0 K is absolute zero, which is the theoretical point where all molecular motion ceases. It is equivalent to -273.15°C and -459.67°F.
So, while 0 K represents the absolute absence of thermal energy, 0 in Celsius and Fahrenheit simply designates specific points on those respective scales.
