temperature measurement starting at absolute zero (total absence of heat).

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 mathematical expression that defines the physical state of a homogeneous substance by relating volume to pressure and absolute temperature for a given mass of the material.

n: a constant number, mathematically the product of the total volume and the total pressure divided by the absolute temperature for 1 mole of any ideal gas mixture of ideal gases at any temperature.

n: 1. a gas whose molecules are infinitely small and exert no force on each other. 2. a gas that obeys Boyles law and Joules law. Also called a perfect gas.

a theoretical gas that perfectly obeys PV=RT/m, where V is the specific volume, T is the absolute temperature, R is the universal gas constant, and m is the molecular weight.

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.
