| What are the 3 States of Matter? | -Solid
-Liquid
-Gas |
| What is different in the States of Matters? | -Simply only the
Energy
Arrangement |
| What are Physical Changes? | -Simply just changing the State that Particles were in
-Example, Melting |
| Explain the Arrangement and Forces in a Solid | -Has Strong Forces of Attraction, that hold the Particles very Close together in a Fixed Regular Arrangement
-Particles have a Low Amount of Energy in terms of Kinetic Energy, so they can only Vibrate if most |
| Explain the Arrangement and Forces in a Liquid | -Forces of Attraction between the Particles are Weaker, so the Particles can Move and Slid on top of each other, whilst being still Close
-They have More Energy in terms of Kinetic Energy, so they can Move in Random Directions, at Low Speeds |
| Explain the Arrangement and Forces in a Gas | -Virtually no Force of Attraction between the Particles, so that means the Particles can Fly Around
-They have most amount of Energy, in terms of Kinetic Energy. They can travel in High Speeds in Different Directions |
| What exactly is the Thermal Energy Store? | -Its literally the Kinetic Energy Stores. It holds the Thermal Energy |
| What happens when you heat a Liquid, in terms of Energy Stores | -Energy is given to the Kinetic Energy Stores, allowing them to move even Faster.
-When enough Particles can overcome the Attraction, big Bubbles of Gas can Form [Boiling] |
| What does working with a Closed System mean? | -Simply means that no Particles can Escape, and no new Particles can Enter |
| Is the Mass affected by changing State? | -No
-This is because the Mass of a Substance is the Mass of the Particles, and the Particles aren't changing, just being Rearranged |
| Does Density change with the Changes of States? | -Yes
-Since the Volume also can change because
-A Solid has the Particles closer than a Liquid
-A Liquid has the Particles closer than a Gas
-Water and Ice, are the 2 Exceptions |
