Flashcards
Solid State
Solid State
A state of matter with a fixed volume and shape, due to strong attractive forces between particles, allowing it to resist changes in shape and volume. Particles are closely packed and vibrate, producing sound.
Gas State
Gas State
A state of matter with no fixed shape or volume, taking on the shape of its container. Particles move freely with weak attractive forces, expanding or contracting with temperature and pressure changes.
Liquid State
Liquid State
A state of matter with a fixed volume but taking on the shape of its container. Particles are less densely packed than solids and move more freely with weaker attractive forces.

Study Notes
Phases of Matter
- Matter exists in four primary phases: solid, liquid, gas, and plasma.
- Solids have a definite volume and shape. Strong attractive forces between atoms/molecules resist change in shape or volume. Atoms are in a fixed position and vibrate, producing sound. The molecules/atoms/ particles are closely packed and held together by very strong forces.
- Liquids have a definite volume but take the shape of their container. Attractive forces are weaker than in solids allowing particles to flow, while holding a constant volume. The molecules in liquids are less densely condensed and free to move. Liquids can be ideal, meaning they remain viscous regardless of shear stress applied. Other liquids are thixotropic, meaning they resist flowing until agitated, then flow like liquids.
- Gases have no definite volume or shape. They take the shape and volume of their container. Weak attraction forces allow the particles to move freely in all directions. Pressure and temperature affect their volume. Gas molecules move freely, offering no resistance to changes in shape or volume. The molecules in a gas are much farther apart than in solids or liquids.
- Plasmas are the fourth state of matter. They are a collection of gaseous particles at extremely high temperatures (over 100,000°C). They have no definite volume or shape. Particles are electrically charged and move freely. Plasmas are abundant in the universe, for example in lightning, auroras, and some stars.
