Study Notes
States of Matter
- Solid: Particles vibrate in fixed positions, held together by strong attractive forces, resulting in a definite shape and volume.
- Liquid: Particles experience weak forces of attraction, allowing them to move freely. Liquids have a definite volume but take the shape of their container and can flow easily.
- Gas: Particles exhibit very weak attractive forces, are in constant motion, and move randomly, which leads to neither a definite shape nor a fixed volume.
Heating and Cooling
-
Heating: As temperature increases, particles gain energy and vibrate more vigorously. This can lead to transitions between states:
- Melting Point: Temperature at which solid particles break free from their bonds, transitioning to liquid.
- Boiling Point: Temperature at which the bonds in a liquid weaken significantly, allowing particles to escape as gas.
- In fixed pressure scenarios, heating typically results in an increase in pressure.
-
Cooling Gas: When gas cools, particles lose energy, which can lead to:
- Condensation: Process where gas particles lose enough energy to overcome their weak attractions and transition to a liquid state.
- Expansion: Noted when gas particles are heated as they spread out in response to increased energy.
