Web21 mrt. 2024 · temperature absolute temperature scale zero-point energy absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale. WebAbsolute temperatureis based on thermodynamicprinciples: using the lowest possible temperatureas the zero point, and selecting a convenient incremental unit. Celsius, Kelvin, and Fahrenheitare common temperature scales. Other scales used throughout history include Rankine, Rømer, Newton, Delisle, Réaumur, Gas mark, Leidenand Wedgwood.
