Octane ratings don't change from summer to winter, but the gasoline's vapor pressure does. The easiest way to understand vapor pressure is to recognize that when a liquid's vapor pressure is equal ...

Reid vapor pressure (RVP) and true vapor pressure (TVP) of crude oil should be tested when dealing with both its production and storage. The vapor pressure reflects the level of performance of the ...

Federal law prohibits gasoline with a Reid vapor pressure (RVP) greater than 9.0 pounds per square inch to be sold at retail stations from June 1 through September 15. (Geeky side note ...

A crucial physical property of volatile liquids — particularly crude oil, gasoline, gasoline-oxygenate blends, and LPG — is vapor pressure. Vapor pressure is accurately determined because of several — ...

The condensing pressure is the pressure at which the refrigerant is phase changing from a vapor to a liquid. This phase change is referred to as condensation. Thus the term condensing pressure. This ...

The pressure of this water gas in equilibrium is called the vapor pressure (assuming it's all water gas and no air in the container). You can see evidence of this water vapor in a closed container ...

The more pressing fundamental difficulty in producing a functional marijuana breath test has been that the vapor pressure of THC molecules prove to be notoriously difficult to identify.

The exact hue depends on the mercury vapor pressure and usually contains a fair amount of ultraviolet light. These tubes have an interesting history dating back to 1901, the year [Peter Cooper ...
