## zero

[ze´ro]
1. the absence of all quantity or magnitude; naught.
2. the point on a thermometer scale at which the graduations begin. The zero of the Celsius (centigrade) scale is the ice point; on the Fahrenheit scale it is 32 degrees below the ice point.
absolute zero the lowest possible temperature, designated 0 on the Kelvin or Rankine scale; the equivalent of −273.15°C or −459.67°F.

## ab·so·lute ze·ro

the lowest possible temperature, that at which the form of translational molecular motion constituting heat is assumed no longer to exist, determined as -273.15°C or 0 kelvin.

## absolute zero

the temperature at which all molecular activity except vibration ceases. It is a theoretical value derived by calculations and projections from experiments with the behavior of gases at extremely low temperatures. Absolute zero is estimated to be equal to -273° C or -460° F.

## Absolute Zero

The lowest possible temperature—0º Kelvin, -273.15º Celsius, -459.67º F. At absolute zero, all molecular motion stops.

## ab·so·lute ze·ro

(ab'sŏ-lūt' zēr'ō)
The lowest possible temperature; the temperature at which the form of translational motion constituting heat is assumed no longer to exist, determined as -273.15°C or 0° Kelvin.

## absolute zero

the lowest possible temperature for all substances, at which their molecules possess no heat energy. -273.15 °C is usually accepted as absolute zero.

## zero

the point on a thermometer scale from which the graduations begin. The zero of the Celsius (centigrade) scale is the ice point; on the Fahrenheit scale it is 32° below the ice point.

absolute zero
the lowest possible temperature, designated 0 on the Kelvin or Rankine scale, the equivalent of −273.15° C or −459.67° F.
