Zero 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, taken as zero kelvin.
Aug 10, 2020 · Absolute zero is the lowest possible temperature for all substances, defined as the point where no more heat can be removed. Learn how absolute zero is measured in Kelvin, Celsius, and Fahrenheit, and what happens to matter at very low temperatures.
May 31, 2024 · Absolute zero is the lowest temperature possible, corresponding to −273.15 °C on the Celsius scale and −459.67 °F on the Fahrenheit scale. Learn how absolute zero was discovered, how it affects gases and matter, and how it relates to the Kelvin scale and other thermodynamic concepts.
