n: a hypothetical temperature at which there is a total absence of heal Since heat is a result of energy caused by molecular motion, there is no motion of molecules with respect to each other at absolute zero.

zero point on the absolute temperature scale;equal to -273.16 degrees C, or 0 degrees K (Kelvin),or -459.69 degrees F, or 0 degrees R (Rankine).

n: a temperature scale with the degree interval of the Celsius scale and the zero point at absolute zero. On the kelvin scale, water freezes at 273.16. and boils at 373.16.. See absolute temperature scale.

n: a temperature scale with the zero point at absolute zero. On the Rankine scale, water freezes at 491.60� and boils at 671.69�. See absolute temperature scale, absolute zero.

n: a spot on the bottom of a storage tank or on the datum plate that is directly below the reference point on the hatch. This location is where the innage bob comes to rest when the tank is gauged and serves as the zero point for all innage measurements.

v: to bring a differential pen to the zero point on an orifice chart.

n: on an orifice chart, the point at which no differential pressure is exerted on the differential pen.
