Absolute Zero
Reference from the original Physics I textbook.
- Absolute Zero
Absolute zero is 0 K, equal to −273.15 °C. It is the lower limit of the thermodynamic temperature scale. It does not imply that every system has zero internal energy or that all quantum motion vanishes.

Absolute zero
Absolute zero is zero kelvin, the lower limit of thermodynamic temperature in the models used here. It corresponds to minus 273.15 degrees Celsius and does not mean all quantum motion disappears. For example, an ideal-gas pressure-versus-Celsius graph can be extrapolated toward this limit, although a real gas may condense before reaching it.
