Diversity of Matter

A set of flashcards covering the diversity of matter, including definitions, classifications, and the roles of solids, liquids, and gases in various contexts.

Materials

Substances used to make objects or products, which can be natural or synthetic.

Classification of materials

Grouping materials into three main states: solids, liquids, and gases.

Solid

A state of matter with closely packed particles, definite shape and volume, and strong intermolecular forces.

Liquid

A state of matter with particles that are close together but can move past one another, allowing it to have a definite volume but no fixed shape.

Gas

A state of matter with particles that are far apart and move freely, resulting in no definite shape or volume.

Intermolecular forces

Forces that hold particles together; they are strong in solids, weaker in liquids, and very weak in gases.

Compressibility

The ability of a substance to decrease in volume under pressure; gases are highly compressible while solids are not.

Density

The mass per unit volume of a substance; solids generally have higher density than liquids and gases.

Hydration

The process of providing or maintaining moisture in the body, primarily through water intake.

Importance of liquids

Liquids play crucial roles in hydration, digestion, lubrication, transportation, and hygiene in human life.

Table salt

A solid that flavors food, serves as a preservative, and provides essential sodium for bodily functions.

Dry ice

Solid carbon dioxide used for refrigeration and preventing flammable gases from igniting.

Kinetic energy

The energy that particles possess due to their motion; lower in solids and higher in gases.

Particle arrangement

The specific way in which particles are organized in solids, liquids, and gases, affecting their properties.

Fluid

A substance that flows and has no fixed shape; includes liquids and gases.

Definite shape

A characteristic of solids; they maintain a fixed form that does not change unless physically altered.

Lifeblood of industry

Materials serve as fundamental components across various industries like construction, manufacturing, and transportation.
