Study Notes
States of Matter Overview
- Matter exists in three primary states: solids, liquids, and gases, defined by shape and volume.
Solids
- Solids possess a definite shape and a definite volume.
- The particles in a solid are closely packed together, which restricts their movement.
- Although particles in solids are not motionless, they vibrate slightly in place.
- Crystalline solids have particles arranged in a regular repeating pattern, such as salt.
- Amorphous solids have particles that do not form a regular pattern, such as rubber.
- Crystalline solids melt at specific temperatures, while amorphous solids soften or change into another substance when heated.
Liquids
- Liquids have a definite volume but take the shape of their container.
- The property of liquids to flow results from freely moving particles.
- A fluid is defined as any substance that flows, which includes both liquids and gases.
- Surface tension in liquids is caused by the inward pull among molecules, allowing the surface to behave as an elastic layer.
- For example, water striders can "walk" on water due to surface tension.
- Viscosity is a measure of a liquid's resistance to flow, influenced by particle size, shape, and inter-particle attractions.
- Liquids with high viscosity (e.g., honey) flow slowly, while those with low viscosity (e.g., water) flow quickly.
Gases
- Gases have neither a definite shape nor a definite volume.
- The properties of gases allow them to flow freely, as demonstrated by the breathing process where air moves in and out of the body.
