Article #1

There are six phases or states of matter but students in high school chemistry only need to focus on solids, liquids, gases, and plasma.<ref>Electric Universe</ref> Four states of matter are thermal whereas Bose-Einstein and filament are theoretical. Liquids and solids are often referred to as condensed phases because the particles are very close together. Gases, in contrast, do not behave as condensed phases and are studied separately. Adding energy to the solid phase, the substance goes through a phase change.


Article #2

Solutions are homogeneous mixtures. Three conditions are necessary to describe a solution: solute, solvent, and temperature. The substance dissolved is called the solute and the dissolving medium is called a solvent.


Major Topics
