solids, liquids, and gasses.
2. Explain the properties of a solid, liquid, and a gas. Talk about the movement of particles.
Solids- hard; particles are in a tight, organized arrangement
Liquids- free flowing; fluid; particles are close to each other, but not in a tight arrangement
Gasses- particles move rapidly, and have much larger spaces between each other than liquid or solid particles
3. Changing the state of matter is a physical change. When energy (in the form of heat) is added or taken away matter can change from one state to another.
It will be a physical change because you are not changing the chemical build-up of the matter, you are just changing the form it is in. Adding or taking away energy can change the state of matter. For example, if you add heat to ice, you get a liquid (water), and if you have enough heat, the water will turn to a gas. An example of taking away energy is condensation. You are taking energy away from the gas to turn in into a liquid.
