Properties of Matter - Lesson 2

Flashcards covering the particulate nature of matter, classification of properties (physical, chemical, intensive, extensive), and types of matter (pure substances and mixtures).

__________ is the material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena.

Matter

The three types of particles composing matter mentioned in the lesson are atoms, molecules, and __________.

ions

A __________ is a positively charged ion that results from the loss of electron(s).

cation

An __________ is a negatively charged ion that results from the gain of electron(s).

anion

A __________ property can be observed or measured without changing the composition of matter.

physical

A __________ property describes the "potential" of matter to undergo some chemical change or reaction by virtue of its composition.

chemical

An __________ property is a type of physical property that will change if the amount of matter changes.

extensive

An __________ property is a type of physical property that will be the same regardless of the amount of matter.

intensive

Mass and volume are examples of __________ properties.

extensive

Color and melting point ($115.2^\text{o}C$ for sulfur) are considered __________ properties.

intensive

A __________ has a constant composition, and all specimens of it have exactly the same makeup and properties.

pure substance

A __________ is composed of two or more types of matter that can be present in varying amounts and can be separated by physical changes.

mixture

Air, brass, steel, and vinegar are examples of __________ mixtures.

homogeneous

Chocolate chip cookies, pizza, and tossed salad are examples of __________ mixtures.

heterogeneous

Measuring the __________ of a gold ring ($density = mass/volume$) is a way to identify matter using a physical property.

density

The ability of iron to __________ when exposed to air and moisture is an example of a chemical property.

rust

A safety label warning that a cleaning product can __________ dangerously when mixed with bleach describes a chemical property.

react

The characteristic of copper that allows __________ to flow through it efficiently is a physical property.

electricity
