Flammable liquids specific gravity

Alkenes — Also known as olefins, and denoted as C H2 the compounds are unsaturated hydrocarbons with a single carbon-to-carbon double bond per molecule. The alkenes are very similar to the alkanes in boiling point, specific gravity, and other physical characteristics. Like alkanes, alkenes are at most only weakly polar. Alkenes are insoluble in water but quite soluble in nonpolar solvents like benzene. Because alkenes are mostly insoluble liquids that are lighter than water and flammable as well, water is not used to suppress fires involving these materials. Because of the double bond, alkenes are more reactive than alkanes. 

The penetration and cooling action of water is required with Class A fires, e.g. those involving paper, wood, textiles, refuse. Extinguishment of a Class B fire can be achieved by the smothering action of dry chemical, carbon dioxide or foam. Most flammable liquids will float on water (refer to Table 5.1 under Specific gravity ), so that water as a... 

UL 2085, Protectedf Aboveground Tanks for Flammable and Combustible Liquids, covers shop-fabricated, aboveground atmospheric protected tanks intended for storage of stable, flammable or combustible liquids that have a specific gravity not greater than 1.0 and that are compatible with the material and construction of the tank. 

Inflammability. See Flammability initiation Sensitiveness. NGc is very sensitive to initial impulse, and NG is exploded, both in a liquid condition and as in Dynamite by the weakest common cap, a No 1, even without confinement (Ref 7, p 226 Ref 16) Magnetic Rotation at 12.6° specific gravity 0.6686 molecular rotation 3-7681 (Ref 5, p 1200 Ref 19, p 132)... 

Stable, low boiling, colorless, heavy, mobile, toxic liquid. Use with adequate ventilation. Chloroform-like odor. Non-flammable, nonexplosive, and noncombustible. Bolling point is 86.7C. Specific gravity is 1.456-1.462. Flash point none. Miscible with all common organic solvents practically Insoluble in water. 

Gasolines — A mixture of volatile, flammable liquid hydrocarbons used primarily for internal combustion engines and characterized by a flash point of approximately -40A and a specific gravity of 0.65 to 0.75. 

Physical changes involve changes in the physical state of the chemical, bnt do not produce a new substance, snch as the physical transformation from a liqnid to a gas or a liquid to a solid. Physical properties include specific gravity, vapor pressure, boiling point, vapor density, melting point, solubility, flash point, fire point, auto-ignition temperatnre, flammable range, heat content, pH, threshold limit valne (TLV), and permissible exposnre level (PEL). 

A term often associated with hazardous materials and water is miscibility. If a chemical is miscible with water, it will mix with water, which could make clean up difficult. If the chemical is not miscible with water, it will form a separate layer. The layer will form on top or on the bottom of the water, depending on the specific gravity of the liquid. Most flammable liquids are lighter than water and immiscible, so they float on the surface. 

Isopropyl ether (diisopropyl ether) is a colorless, volatile liquid, which is slightly soluble in water. The specific gravity is 0.7, which is lighter than water. It is highly flammable, with a wide flammable range of 1.4 to 21% in air. The boiling...
