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.

Jan 5, 2026 · 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.

ABSOLUTE ZERO definition: the temperature of −273.16°C (−459.69°F), the hypothetical point at which all molecular activity ceases. See examples of absolute zero used in a sentence.

This temperature, where there's no thermal energy at all, is called absolute zero. [2] Numerically, this is written as 0 K, -273.15 °C, or -459.67 °F.

Absolute zero is the theoretical lowest temperature possible, defined as 0 Kelvin (K), where molecular motion ceases completely. At this point, a system's entropy reaches its minimum …

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.

May 26, 2025 · Absolute zero is the theoretical temperature at which a system's fundamental particles are in the lowest possible energy state, possessing no thermal energy and minimal …
