What is Reid Vapor Pressure?

Correct Answer: Option B — a measurement of the amount of flammable vapors given off by a liquid at a certain temperature

Reid Vapor Pressure (RVP) is the absolute vapor pressure exerted by a liquid at 100°F (37.8°C). It serves as a standardized measure of a liquid's volatility and its tendency to produce flammable vapors, which is essential for assessing fire hazards and determining proper tank venting requirements under USCG regulations.
