Experts use it when evaluating water scarcity. This metric can describe the total available water resources each country contains.

Material efficiency is a description or metric ((Mp) (the ratio of material used to the supplied material)) which refers to decreasing the amount of a particular material needed to produce a specific product. [1] Making a usable item out of thinner stock than a prior version increases the material efficiency of the manufacturing process.

The level of water scarcity in a certain country was determined based on thresholds: If the amount of renewable water in a country is below 1,700 m 3 per person per year, that country is said to be experiencing water stress; below 1,000 m 3 it is said to be experiencing water scarcity; and below 500 m 3, absolute water scarcity.

Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [26] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.

Ton is any of several units of measure of mass, volume or force. It has a long history and has acquired several meanings and uses. As a unit of mass, ton can mean: the long ton, which is 2,240 pounds (1,016.0 kilograms) the tonne, also called the metric ton, which is 1,000 kilograms (about 2,204.6 pounds) or 1 megagram.
