One property of matter is the state it is in. No, not the state, as in Michigan or Delaware, but rather the phase of something. I or instance, water is normally in a liquid state or phase, but can also be in a solid state as ice. Water in a gas state is what we know of as steam or water vapor. Let's look closer af each state of matter.
Your toys, your pencil, and your desk are all examples of solids. The particles inside of a solid are packed so tightly together that they never move. That means, regardless of the shape of the container, the shape will stay the same. This is called having a definite shape. Solids also have a definite space, so their volume is always constant.
Liquid
Liquids are very different from solids. Instead of staying together as one sold shape, it flows and takes on the shape of whatever container it is in. Therefore, it has no definite shape. The particles inside of a liquid are close together, but not packed tightly like a solid. There is also definite space, so the volume is also always the same.
Cas is a state of matter where the particles are really far apart and constantly bouncing off one another. These particles are free flowing and invisible. You could put your hand right through gas! It doesn't have a definite shape. so it just changes based on its container. Since gas can be compressed. its volume can actually change. Some examples of gas is the air you breathe caled oxygen and the air you exhale caled carbon dioxide. Copyright The Owl Teacher 2015
Ice is an example of a solid.
Water, soda, and coffoo are all examples of liquids.
