Structure and Properties of Matter Quiz

solid particle arrangement

The particles are tightly packed.

The particles do not move around.

liquid particle arrangement

The particles are close together.

The particles vibrate, move, and slide past each other.

gas particle arrangement

The particles are very separated.

The particle vibrate and move quickly.

condensation

The change of state from a gas to a liquid

Matter

anything that takes up space and has mass

sublimation

A change of state from solid to gas

deposition

A change of state from gas to solid

chemistry

The study of the properties of matter and how matter changes

mass

the amount of matter in an object

volume

The amount of space an object takes up

weight

A measure of the force of gravity on an object

physical properties of matter

how matter is described according to physical characteristics; characteristics that can be observed without changing the substance into something else; ex. luster

physical properties examples

viscosity, conductivity, malleability, hardness, melting point, boiling point, and density

physical change

A change in a substance that does not change its identity

Chemical Properties of Matter

characteristics that can be observed when a substance interacts with another substance; ability to react; inability to react; usually hidden

chemical change

A change that occurs when one or more substances change into entirely new substances with different properties.

phase change

a change from one state (solid or liquid or gas) to another without a change in chemical composition

particles

extremely small units of matter (general term)

Viscosity

A liquid's resistance to flowing

surface tension

A measure of how difficult it is to stretch or break the surface of a liquid

amorphous solid

A solid made up of particles that are not arranged in a regular pattern

crystalline solid

A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern

thermal energy

The total energy of motion in the particles of a substance (heat energy)

density

Mass per unit volume (D\=M/V) (The amount of matter in a given volume)

physical properties of matter

characteristics of matter that are observable or quantifiable

chemical properties are observed…

by performing a chemical reaction

physical properties are observed…

without changing the composition of the matter

intensive

same regardless of the amount of matter

extensive

changes according to amount of the substance

intensive physical properties

color, odor, density, luster, thermal conductivity, malleability, ductility, solubility, elasticity

extensive physical properties

mass, volume, length, shape
