A solution of a strong alkaline, such as sodium hydroxide, at concentration 1 mol dm â3, has a pH of 14. Thus, measured pH values will lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible.
The Saffir-Simpson scale measures the intensity of a hurricane. Wind speed is measured on a scale of 1-5 to give an estimate of potential property damage and flooding along the coast. The Categories are as follows:Category One Hurricane: Winds 74-95 mph.Category Two Hurricane: Winds 96-110 mph.ind speed is measured on a scale of 1-5 to give an estimate of potential property damage and flooding along the coast. The Categories are as follows: Category One Hurricane: Winds 74-95 mph.
Beaufort scale-an international scale of wind force from 0 (calm air) to 12 (hurricane). wind scale. calm air, calm-wind moving at less than 1 knot; 0 on the Beaufort scale.n. 1. (Physical Geography) meteorol an international scale of wind velocities ranging for practical purposes from 0 (calm) to 12 (hurricane force). In the US an extension of the scale, from 13 to 17 for winds over 64 knots, is used.eaufort scale-an international scale of wind force from 0 (calm air) to 12 (hurricane). wind scale. calm air, calm-wind moving at less than 1 knot; 0 on the Beaufort scale.
