From the expression p = po (1 + at) it follows that if a substance remains in a gaseous state up to a temperature of -273.15 ° C, its pressure at this temperature should become equal to zero. This temperature was taken as the origin of the new temperature scale – absolute zero, and 1 kelvin (K), equal to 1 ° С, was taken as the unit of temperature on the absolute scale.
