What is Chemistry? Matter and Property Classification

Vocabulary flashcards covering key terms about matter, physical properties, and chemical properties from Page 1 notes.

Chemistry

The science that studies matter, its properties, composition, and changes.

Matter

Anything that has mass and occupies space (has volume).

Mass

The amount of matter in an object; commonly measured in grams.

Volume

The amount of space that matter occupies; commonly measured in liters or cubic centimeters.

Physical properties

Characteristics that can be observed or measured without changing the substance.

Density

Mass per unit volume.

Elasticity

The ability of a material to return to its original shape after deformation.

Luster

The shiny or reflective quality of a material.

Hardness

Resistance to scratching or indentation.

Temperature

A measure of the hotness or coldness of a substance; related to thermal energy.

Viscosity

A liquid’s resistance to flow; thickness of a liquid.

Melting point

The temperature at which a solid changes to a liquid.

Boiling point

The temperature at which a liquid changes to a gas.

Malleability

The ability to be hammered or pressed into shape without breaking.

Ductility

The ability to be drawn into wires.

Conductivity

The ability to conduct heat or electricity.

Solubility

The ability of a substance to dissolve in a solvent.

Chemical properties

Characteristics that describe how a substance changes or reacts to form new substances.

Combustion

A chemical reaction with oxygen that releases heat and light.

Rusting

Oxidation of iron forming iron oxide; a chemical change.

Oxidation

A chemical reaction involving loss of electrons or reaction with oxygen.

Flammability

The ability of a substance to burn.

Reactivity

The tendency of a substance to undergo chemical change.
