States Of Matter

            The definition of matter is something that takes up space and has a mass.
             has to have inertia and weight when gravity is present. Matter is commonly.
             known to exist in three states: solid, liquid, and gas. Scientists also acknowledge.
             two other states: plasma and Bose-Einstein condensate (A). The general properties.
             of matter come from having mass and taking up space. Even though a substance.
             might change its state, it still consists of the same atoms. The state of matter.
             depends on its temperature, which is the average kinetic energy of the substances.
             molecules (B).
             The molecules of a solid are held closely together, and don’t have much.
             free space to move. This is why a solid holds its shape. The atoms do not have.
             enough kinetic energy to move out of their positions. This limitation gives a solid.
             a limited volume and shape. The particles of most solids are arranged in.
             duplicating geometric patterns called crystals (C). As the temperature of a solid.
             increases, the molecules eventually free themselves from their fixed position and a.
             phase change occurs. Depending on the element, the change from solid to liquid.
             will happen at a specific temperature known as the melting point (B). When that.
             happens, the substance is classified as a liquid.
             The molecules of a liquid have more room to move, but are still held.
             loosely held together. Because the liquids particles can move freely, they have no.
             definite shape (B). The molecules have the ability to flow, and will take on the.
             shape of their container. The atoms are still somewhat close together, and have a.
             definite volume (A). At a certain temperature, particles gain enough energy to.
             become free of the bond to other particles. When liquid gains enough kinetic.
             energy to become a gas, it is said to be boiling. Different substances have distinct.
             boiling points, depending on the amount of energy needed to make the molecules.
             move. Once the molecules escape the bond of the other particles, the matter is.
