Answer:
a. Humidity is the concentration of water vapor present in the air. ... Relative humidity, expressed as a percentage, indicates a present state of absolute humidity relative to a maximum humidity given the same temperature.
b. An atmosphere (from Ancient Greek ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'ball' or 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
2. With physical filtration, water is strained, often through a gauze-like membrane, to remove larger particles. With chemical filtration, water is treated with patented smart technology to remove impurities. Different types of filtration are used to remove different types of contaminants.
3. All water -- no matter if it comes from a natural spring, artesian well, or regular tap -- may have trace but safe amounts of minerals, bacteria, pesticides, and other contaminants. Distilling rids water of all those impurities. It also removes more than 99.9% of the minerals dissolved in water.
4. Many substances that are hazardous to human health can enter water supplies. Chemical waste from factories is sometimes dumped into rivers and lakes, or directly into the ground. As the pollutant travels downstream it is diluted by the addition of water. ...
5. In chemistry, a condenser is laboratory apparatus used to condense vapors — that is, turn them into liquids — by cooling them down. ... In distillation, a mixture is heated until the more volatile components boil off, the vapors are condensed, and collected in a separate container.
