Study Notes
States of Matter
- Particle: A minute unit that constitutes all forms of matter.
- Solid: Maintains a definite shape and volume; examples include rocks.
- Liquid: Adapts to the shape of its container and flows; water is a common example.
- Gas: Lacks a definite shape or volume; examples include air, which is typically invisible.
- Plasma: A highly energized state of matter, found in stars like the sun.
Phase Changes
- Melting: The process where a solid transforms into a liquid; seen when ice melts to form water.
- Freezing: When a liquid converts into a solid; for instance, water solidifies to become ice.
- Condensation: The transition of gas into liquid; occurs when water vapor forms droplets on a cold surface.
- Evaporation: The change from liquid to gas; an example is water evaporating under sunlight.
- Sublimation: When a solid turns directly into a gas without passing through the liquid state; this occurs with dry ice.
- Deposition: The direct transformation from gas to solid; an example is the formation of frost.
- Ionization: The process where a particle gains or loses electrons, illustrated by the occurrence of lightning.
