Study Notes
States of Matter
- Matter can be classified into three states: solids, liquids, and gases.
- Solids have a fixed shape and volume, cannot be compressed, and cannot be poured.
- Liquids take the shape of their container, can be poured, cannot be compressed, and have a fixed volume.
- Gases flow like liquids, fill any container, are easily compressed, and have variable volume.
Particle Theory
- The particle theory explains how particles are arranged differently in solids, liquids, and gases.
- Solids have particles in fixed positions, tightly packed, and held together strongly.
- Liquids have particles touching, held together weakly, allowing movement past each other.
- Gases have particles far apart, no attractive forces between them, allowing free movement and expansion.
Changes of State
- Matter can change state by adding or removing heat.
- Heating can cause a solid to melt into a liquid or a liquid to vaporize into a gas.
- Cooling can cause a gas to condense into a liquid or a liquid to freeze into a solid.
Modeling Particles
- Particle theory can be modeled by arranging people in different ways to represent solids, liquids, and gases.
- Solid models should have individuals in a fixed pattern, close together, and unable to move.
- Liquid models should have individuals touching but able to move past each other.
- Gas models should have individuals spread out, with no contact, and free to move in any direction.
