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 ignition temperature is affected by the chemical properties of the flammable liquid. When a flammable liquid is in its liquid state, it will not ignite. It will only burn when in its gaseous state.In addition to ignition temperature, other properties associated with the flammability of a liquid are its flash point, flammable range, and vapor density.The flash point is the temperature at which a flammable liquid vaporizes and is therefore able to ignite.Liquids with a flash point under 40 Â°C are considered combustible liquids. Gasoline has a flash point of about -45 Â°C.he ignition temperature is affected by the chemical properties of the flammable liquid. When a flammable liquid is in its liquid state, it will not ignite. It will only burn when in its gaseous state.
