Hydrogen - Element information, properties and uses

Hydrogen is an essential element for life. It is present in water and in almost all the molecules in living things. However, hydrogen itself does not play a particularly active role. It remains bonded to carbon and oxygen atoms, while the chemistry of life takes place at the more active sites involving, for example, oxygen, nitrogen and phosphorus.

How does dry ice work? | HowSfWorks

­Dry ice is frozen carbon dioxide.A block of dry ice has a surface temperature of -109.3 degrees Fahrenheit (-78.5 degrees C). Dry ice also has the very nice feature of sublimation-- as it breaks down, it turns directly into carbon dioxide gas rather than a liquid.The super-cold temperature and the sublimation feature make dry ice great for refrigeration.

Uses of Helium - Uses Of

Helium is one of the most common elements in the universe. It is called a noble gas because it doesn’t chemically interact with elements. Its atomic nuer is 2 and the weight is 4.002. In its natural state, it doesn’t have any smell, taste or color. Common Uses of Helium Evidence shows that the human voice can be changed with a bit of helium. The gas is also used as light weight aircraft

How Paint is Made | Paint Manufacturing Process | …

Enamel paint is made from an alkyd resin that is dissolved in a solvent. As the solvent evaporates in the first stage, it forms a tacky lacquer. The resin reacts with the oxygen in the air and forms a hard coating. Coating paints have two components that are unreactive alone. However, when they are placed together, they undergo a chemical reaction.
