Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A packaging gas is a gas used to pack sensitive materials in a modified atmosphere. It is usually inert, or of a nature that protects the packaged goods, thus inhibiting reactions such as spoilage. Some may also serve as propellant for aerosols like whipped cream. Gas is one of three classical states of matter. Near absolute zero, a substance exists as a solid. As heat is added to this substance it melts into a liquid at its melting point (see phase change), boils into a gas at its boiling point, and if heated high enough would enter a plasma state in which the electrons are so energized that they leave their parent atoms from within the gas.
