Matter is anything that takes up space and has mass .
We can measure the mass and the volume (the amount of space the matter occupies).
The matter of a liquid is not as tightly packed together, so the liquid can flow and when poured into a container, will fill the container’s shape.
The matter of gases is spread even farther apart than a liquid. It also has no definite shape and will spread out to fill its container.
When we apply heat energy to a solid (like ice), it melts into a liquid.
When we apply more heat energy, the liquid expands (becomes larger) and evaporates and becomes a gas (water vapor).
As water vapor cools, condensation takes place.
When we cool a gas down (like water), it contracts (becomes smaller) and changes into a liquid, and when we cool the liquid some more, it freezes into a solid (ice).
When matter changes from one state to another, these changes are referred to as physical changes.
