Study Notes
Overview of States of Matter
- There are four main states of matter: solid, liquid, gas, and plasma
- These states are determined by the arrangement of particles and their energy levels
Solid State
- Particles are closely packed and have a fixed position
- Particles vibrate in place, but do not change position
- Has a fixed shape and volume
- Examples: rocks, metals, ice
Liquid State
- Particles are close together, but are free to move past each other
- Particles have some freedom of movement, but are still attracted to each other
- Takes the shape of its container, but has a fixed volume
- Examples: water, oil, juice
Gas State
- Particles are widely spaced and are free to move in any direction
- Particles have a lot of energy and are not attracted to each other
- Has neither a fixed shape nor a fixed volume
- Examples: air, helium, oxygen
Plasma State
- Particles are ionized, meaning they have lost or gained electrons
- Particles are highly energetic and move freely
- Found in high-temperature environments, such as stars and lightning
- Examples: neon signs, plasma TVs, stars
Phase Changes
- Melting: solid to liquid
- Freezing: liquid to solid
- Evaporation: liquid to gas
- Condensation: gas to liquid
- Sublimation: solid to gas
- Deposition: gas to solid
