what is one example matter can be changed
We'll start by looking at changes in matter, but as you'll see, it is not possible to talk about changes in matter without talking about adding or releasing energy. Matter can be changed two ways, physically and chemically. Let's discuss Physical changes first. Physical changes. Physical changes occur when matter changes from one state of matter to another state of matter by adding or losing thermal energy. In a physical change of state matter retains its original identity, it just changes the state of matter it is in. For example: Imagine a beaker of ice sitting on a warm hot plate. As you watch the ice, this solid water makes a physical change of state to liquid water.
