The Vapor Density comparisons are only valid when the fuel escaping is at the identical temperature as the bordering air alone. Should the chemical is escaping from a container where it absolutely was pressurized or refrigerated, it may well first escape and behave being a weighty fuel and sink within the air (whether or not it has a Vapor Density value fewer than one). Also, the Specific Gravity comparisons are for new water (density 1.0 g/mL). If your spill is in salt water (density about one.027 g/mL), you should alter the point of comparison. There are many chemicals that will sink in fresh water and float in salt water.
To start with identified in 1786 by Scheele, who extracted it from the dye Prussian blue – and instantly died from exposure towards the vapours
