		A convenient standard quantity is the mole, the mass of gas in grams equal to the molecular mass in amu.
		For example in the heat-work example, the final state is characterized by a specific temperature (a state variable) regardless of whether it was brought to that state by heating, or by having work done on it, or both.

	Re: when was the first time that Standard Temperature and Pressure was used?
		What this means is that there is not a lot of use in specifying a gas volume as a measure of the amount of gas unless you also specify the temperature and pressure that the volume of gas is measured at.
		A small correction has to be applied to mercury column pressure measurements to allow for expansion of the mercury with temperature.
		Even so, it is a bit unfortunate that the standard temperature for STP is an uncomfortably cool one, and, more importantly, that it does not conform to the 25 deg C standard used for so many other chemical quantities.

		Simultaneous vertical profiles of the scattering coefficient of the air at one wavelength between 0.475 and 0.75 mu m, temperature, pressure, and relative humidity have been measured from 1973 to 1978, mostly in Central and Western Europe.
		From these results, vertical profiles of the normalized (to air at standard temperature and pressure) scattering coefficients of dry particles were derived.
		These standardized scattering coefficients are independent of the thermodynamic state of theatmosphere and thus strictly comparable.

	Standard Pressure Volume Temperature Data for Polymers (Site not responding. Last check: )
		From the IntroductionPVT data consists of records of the specific volume of a material (or its inverse, the density) as a function of pressure and temperature.
		There are many reasons why the specific volume of a material will undergo changes: changes in the temperature and pressure (thermal expansion and compression), phase changes (solid-solid phase transitions, melting, crystallization, glass transitions, mesophase transitions), degradation reactions, and many more.
		Polymers are sensitive to pressure: the volume itself, the pressure dependence of transition temperatures, and the kinetics of phase transitions are all significant, not only from a scientific point of view, but also for practical applications in polymer engineering, such as processing.
