Dear abedalqader,
"The absolute zero the temperature at which an ideal gas would exert no pressure."The Kelvin scale of temperatures is defined in terms of the triple point of water, T3 = 273.16° (where the solid, liquid, and vapor phases coexist), and absolute zero. Temperature is measured most simply via the constant-volume ideal gas thermometer.In which a small amount of gas is introduced (in order to limit the effect of interactions between molecules) and then sealed off, and the gas pressure P referenced to its value at the triple point P(T3) is measured.The ideal gas law applies if the molecules in a gas exert no forces on one another and if they are not attracted to the walls. Absolute zero is the temperature at which the pressure of a truly ideal gas would vanish.
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 any temp,scale having absolute zero for its zero point is termed an absolute temperature scale or a thermodynamic scale.In the International System of Units, the Kelvin (K) scale is the standard for all scientific temperature measurements. Its fundamental unit, the kelvin, is identical in size to the Celsius degree and is defined as 1/273.16 of the “triple point” of pure water (0.01 °C [32.02 °F])—i.e., the temperature at which the liquid, solid, and gaseous forms of the substance can be maintained simultaneously. The interval between this triple point and absolute zero comprises 273.16 kelvins. The lowest temperature achieved in experiments has been 50 pico kelvin (pK; 1 pK = 10−12 K).
absolute zero, the zero point of the ideal gas temperature scale, denoted by 0 degrees on the Kelvin & rankine temperature scales, which is equivalent to −273.15°C; and −459.67°F;. For most gases there is a linear relationship between temperature and pressure ,i.e. gases contract indefinitely as the temperature is decreased. Theoretically, at absolute zero the volume of an ideal gas would be zero and all molecular motion would cease.In actuality, all gases condense to solids or liquids well above this point. Although absolute zero cannot be reached,temperatures within a few billionths of a degree above absolute zero have been achieved in the laboratory. At such low temperatures, gases assume nontraditional states.
