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.
