The Phase Change
There are three main stages of matter, solid, liquid, and gas. With these stages of matter are six types of phase changes, two for each stage. When going from solid to a liquid, it is referred to as melting, and when going from liquid to a solid freezing. In melting, the solid’s molecular movement increases while the attraction decreases. In freezing, the molecular movement decreases while the attraction increases. An example of freezing is water turning into ice, and an example of melting is ice turning into water. When a liquid turns into a gas it is termed vaporization, and when a gas turns into a liquid it is called condensation. In vaporization molecular movement increase yet the attraction decreases, and in condensation the molecular movement decreases yet the attraction increases. An example of vaporization is water boiling until it is gone, and an example of condensation is when droplets of water form on the lid of a teapot. When a gas turns into a solid it is entitled deposition, and when a solid turns into a gas it is seen as sublimation. When a gas goes threw deposition its molecular movement decreases substantially while the attraction increases rapidly. When a solid goes threw sublimation its molecular movement increases miraculously as the attraction decreases promptly. These two phase changes are not as common as the other four, but still happen. An example of sublimation is when dry ice turns back into CO2. An example of deposition is frost in the winter forming on a window.
