Absolute zero - Wikipedia
WEBZero kelvin (−273.15 °C) is defined as absolute zero. Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value.
Absolute zero | Definition & Facts | Britannica
WEBAug 14, 2024 · Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to minus 273.15 degrees Celsius and to minus 459.67 degrees Fahrenheit. While all molecular movement does not cease at absolute zero, no energy from that motion is available for transfer to other systems.
What Is Absolute Zero? Temperature in Kelvin, Celsius, and Fahrenheit
WEBAug 10, 2020 · Absolute zero is defined as the temperature at which a cooled ideal gas is in its lowest energy state. In other words, it’s the point at which no more heat can be removed. While boiling point and melting point depend on the nature of a material, absolute zero is the same for all substances.
