In the context of temperature, "0" can have different meanings depending on the scale being used:
-
Celsius (°C): In the Celsius scale, 0 degrees represents the freezing point of water under standard atmospheric conditions.
-
Fahrenheit (°F): In the Fahrenheit scale, 0 degrees is much colder than freezing and does not have a specific physical significance like it does in Celsius.
-
Kelvin (K): In the Kelvin scale, 0 K (absolute zero) represents the theoretical point at which all molecular motion stops. This is the lowest possible temperature and is equivalent to -273.15 °C.
So, "0" does not universally mean "no temperature"; its meaning depends on the temperature scale being used.
