File talk:Vapor ethanol mixtures Fig 4.3.jpg

It should be explained that the mixture vapor pressure given in the graphic is the Reid vapor pressure (RVP) defined as the absolute vapor pressure exerted by a liquid at 100 °F (37.8 °C). This information is important since the pressure exerted by the mixture is a function of temperature.

Please do so. Insert your explanation in the description. Cheers.--Mariordo (talk) 02:59, 14 January 2015 (UTC)
