Corner icon for tutorials on matter. Solids are often hard, liquids fill containers, and gases surround us in the air. How does matter change from one state to another? When the temperature of the water goes up, the molecules get more excited and bounce around a lot more.
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. The key word to notice is “physical”. Matter only moves from one phase to another by physical means. Adding energy can create a phase change in matter. If you place a glass of liquid water on a table, it will just sit there.
