A temperature referenced to absolute zero. Absolute zero is the temperature at which molecular activity ceases. Absolute zero equals 0 Kelvin, -273.15°C, and –459.67°F. All material properties change according to temperature.
The temperature of a body referred to the absolute zero, at which point the volume of an ideal gas theoretically becomes zero. (Fahrenheit scale is minus 459.67°F / Celsius scale is minus 273.15°C). (010)
