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.
An oil reaches its flash point (about 320 degrees C (600 degrees F) for most oils) when tiny wisps of fire begin to leap from its surface. If the oil is heated to its fire point (slightly under 400 degrees C (700 degrees F) for most oils), its surface will be ablaze. 5 people found this useful.
