Properties of Matter Lecture Flashcards

A set of vocabulary flashcards covering the phases of matter, phase changes, and the classification of physical and chemical properties from General Chemistry 1.

Matter

Anything made up of particles that gives its mass and volume.

Solids

A state of matter characterized by highly strong intermolecular forces, a definite shape, a definite volume, and the absence of intermolecular space.

Liquids

A state of matter where intermolecular forces are stronger than gases but weaker than solids, resulting in a definite volume but no definite shape.

Gases

A state of matter with no definite shape or volume, where intermolecular forces are practically non-existent and particles have plenty of free-flowing space.

Plasma

A hot ionized gas consisting of an equal number of positive ions and negative charged electrons.

Bose-Einstein condensate(BEC)

A state of matter created when particles are cooled near to absolute zero.

Sublimation

The phase change where a solid turns directly into a gas.

Deposition

The phase change where a gas turns directly into a solid.

Melting

The phase change where a solid transforms into a liquid.

Fusion/"Freezing"

The phase change where a liquid transforms into a solid.

Vaporization/"Boiling"

The phase change where a liquid transforms into a gas.

Condensation

The phase change where a gas transforms into a liquid.

Physical Properties

Characteristics of substances that can be observed without changing the substance into another substance or changing its chemical composition.

Chemical Properties

Properties observed by changing the substance into another substance, describing the ability of a substance to undergo changes in its identity.

Extensive Properties

Physical properties of matter that depend on the amount of matter present.

Intensive Properties

Physical properties of matter that do not depend on the amount of matter present.

Mass

An example of an extensive physical property that depends on the amount of the substance.

Volume

An extensive physical property that depends on the amount of matter present.

Density

An intensive physical property that does not depend on the amount of the substance.

Malleability

An intensive physical property that describes the ability of a substance to be hammered into thin sheets.

Conductivity

An intensive physical property that determines if a property can be measured without changing the identity of the substance.

Flammability

A chemical property of matter that involves the substance changing identity during observation.
