Simple binary ionic compounds to polyatomic compounds. Students should also have a Periodic table. Click on the compound link to show or hide each formula. We look at five states of matter on the site. Solids are often hard, liquids fill containers, and gases surround us in the air. Each of these states is also known as a phase.
How does matter change from one state to another? Elements and compounds can move from one state to another when specific physical conditions change. When the temperature of the water goes up, the molecules get more excited and bounce around a lot more. If you give a liquid water molecule enough energy, it escapes the liquid phase and becomes a gas.
The extra energy allows the molecules to change states. Have you ever noticed that you can smell a turkey dinner after it starts to heat up? As the energy of the molecules inside the turkey heat up, they escape as a gas. You are able to smell the volatile compounds that are mixed in the air around you.
It’s About the Physical “Phase” describes the physical state of matter. The key word to notice is “physical”. Matter only moves from one phase to another by physical means. Changing the pressure of a system is another way to create a physical change.
