Water is constantly cycling through the atmosphere: it evaporates from the earth's surface and rises into the atmosphere. It condenses into clouds, is blown by the wind, and then falls back to earth as rain or snow. It may sound surprising, but water vapour is the most powerful of the …
WebbImpermeability is defined as the property of a material that it cannot be pervaded by water or other liquids. It is represented with permeability coefficient K which reflects the flow rate of water in the material. Bigger K indicates that water in the material is flowing faster, and the material’s impermeability is weaker.
