BMI is calculated by taking a person's weight and dividing by their height squared. For instance, if your height is 1.82 meters, the divisor of the calculation will be (1.82 * 1.82) = 3.3124. If your weight is 70.5 kilograms, then your BMI is 21.3 (70.5 / 3.3124) (see calculator links below).
Flammable and combustible liquids themselves do not burn. It is the mixture of their vapours and air that burns. Gasoline, with a flashpoint of -40Â°C (-40Â°F), is a flammable liquid. Even at temperatures as low as -40Â°C (-40Â°F), it gives off enough vapour to form a burnable mixture in air. Phenol is a combustible liquid.
The flash point is defined as the fuel temperature at which the equilibrium fuel vapor concentration of its lower flammability limit is attained. In reality the flash point of a chemical is the lowest temperature where enough fluid can evaporate to form a combustible concentration of gas. It is the lowest temperature of oil at which the application of defined test flames causes the vapors above the surface to ignite and the release of vapors at this temperature is not sufficiently rapid to sustain combustion.
