## States of matter and changes of state unit test a answer key

On the web, we look at five different states of matter. Different states of matter with different physical properties include solids, liquids, gases, plasmas, and Bose-Einstein condensates (BEC). Solids are usually strong, liquids fill tanks, and gases fill the air around us. A step is a term used to describe each of these states.
What happens when matter transforms from one state to another? When certain physical conditions change, elements and compounds may transition from one state to another. As a system’s temperature rises, for example, the matter in the system becomes more excited and active. A phase change can occur when matter moves to a more active state when enough energy is forced into a system.
Let’s say you have a glass of water in your hand (H2O). The molecules become more agitated and bounce around a lot more as the temperature of the water rises. A liquid water molecule will escape the liquid phase and become a gas if given enough energy. The additional energy enables the molecules to switch states.
Have you ever noticed how a turkey dinner begins to smell as it begins to heat up? The energy of the molecules within the turkey is released as a gas as they heat up. The volatile compounds that are mixed in the air around you can be smelled.
