  2. 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.

  3. May 31, 2024 · 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.

  4. Aug 9, 2023 · The meaning of ABSOLUTE ZERO is a theoretical temperature characterized by complete absence of heat and motion and equivalent to exactly —273.15°C or —459.67°F.

  5. Aug 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.

  6. Nov 27, 2019 · Absolute zero is defined as the point where no more heat can be removed from a system, according to the absolute or thermodynamic temperature scale. This corresponds to zero Kelvin, or minus 273.15 C. This is zero on the Rankine scale and minus 459.67 F.

  7. 6 days ago · Zero of thermodynamic temperature (0 kelvin) and the lowest temperature theoretically attainable. It is the temperature at which the kinetic energy of atoms and molecules is minimal. It is equivalent to –273.15°C or –459.67°F. See also zero-point energy.

    May 29, 2018 · Absolute zero, 0 degrees Kelvin (K), – 459.67 ° F, or – 273.15 ° C, is the minimum possible temperature: the state in which all motion of particles in a substance is at a minimum. It is also referred to as the temperature at which pressure is zero.

  9. The lowest possible temperature, at which all molecules are have the least possible amount of kinetic energy. Absolute zero is equal to 0°K, −459.67°F, or −273.15°C. At temperatures approaching absolute zero, the physical characteristics of some substances change significantly.

  10. When all of the molecules (or atoms) in a system stop moving completely, that's as cold as they can get. This temperature, where there's no thermal energy at all, is called absolute zero. Numerically, this is written as 0 K, -273.15°C, or -459.67°F.

  11. noun [ U ] us / ˈæb·səˌlut ˈzɪər·oʊ / Add to word list. chemistry. the temperature that scientists believe is the lowest possible and at which all molecules (= smallest units of a substance) stop moving. (Definition of absolute zero from the Cambridge Academic Content Dictionary © Cambridge University Press) Examples of absolute zero.

  12. absolute zero | American Dictionary. noun [ U ] us / ˈæb·səˌlut ˈzɪər·oʊ / Add to word list. chemistry. the temperature that scientists believe is the lowest possible and at which all molecules (= smallest units of a substance) stop moving. (Definition of absolute zero from the Cambridge Academic Content Dictionary © Cambridge University Press)

  13. Absolute zero is the lowest possible temperature where heat energy is absent in a substance. Absolute zero is also known as zero kelvin temperature since it measures zero on the Kelvin scale. Minimal vibrational motion is displayed at this temperature by fundamental particles of nature.

  14. Absolute zero is the temperature at which the particles of matter (molecules and atoms) are at their lowest energy points. Some might think that at absolute zero particles lose all energy and stop moving.

  15. Nov 15, 2018 · It’s simply a measure of how fast the atoms or molecules within a substance are moving — or, to be more precise, the average kinetic energy of those particles. Think of it as a game of atomic...

    Jan 1, 2008 · Those who have studied some physics might remember why minus 459.67 Fahrenheit is called "absolute zero," but for the rest, it's probably a bit confusing.

  17. Absolute zero is the lowest temperature possible. At a temperature of absolute zero there is no motion and no heat. Absolute zero occurs at a temperature of 0 kelvin, or -273.15 degrees Celsius, or at -460 degrees Fahrenheit.

  18. Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0.

  19. May 22, 2019 · The coldest theoretical temperature is called absolute zero, at which the thermal motion of atoms and molecules reaches its minimum. This is a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0.

  20. Discover the fascinating physics of absolute zero, the lowest possible temperature in the universe, and its implications for life.

  21. Definition of absolute zero noun in Oxford Advanced Learner's Dictionary. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more.

  22. Feb 17, 2010 · Absolute zero. Chill things close to the lowest possible temperature and weird things start to happen. New Scientist takes a look at the coldest objects in the universe.

  23. Absolute zero is the lowest possible temperature, when no heat remains. As the temperature of a substance decreases, its molecules move slower, including electrons, protons, and neutrons. At absolute zero, molecules move the slowest they possibly could, though particles never stop moving completely and there is internal energy.

  24. Dec 14, 2022 · Here, over the past few decades, researchers have been contriving ways to reach ever closer to the coldest possible temperature, absolute zero.

  25. 2 days ago · The former defence secretary comes to Rishi Sunak's defence as he is asked why the prime minister has decided not to talk to journalists this weekend.
