Changes in Matter - Physical Properties (Morenberg)

Formula for Volume

• length times width times height or L x W x H

• length plus width plus height or L + W + H

• length divided by width divided by height or L / W / H

• length minus width minus height or L - W - H

Physical Property

• A characteristic of a substance that can be observed without changing its nature.

• A characteristic that can only be observed by altering the substance.

• A property that is always visible under all conditions.

• A feature that defines the chemical reactivity of a substance.

Atom

• The smallest complete component of matter, made up of protons, neutrons, and electrons.

• A large particle that makes up molecules.

• A type of chemical bond between two elements.

• A form of energy that can be converted into matter.

Density

• The amount of mass per unit of volume. It identifies how tightly packed the matter of a substance is.

• The measure of how much space an object occupies.

• The total weight of an object regardless of its size.

• The ability of a substance to float in water.

Matter:

• Anything that has a measurable mass and volume (takes up space).

• A substance that can be seen but not touched.

• An object that exists only in theory.

• A form of energy that cannot be measured.

Gases

• Have a definite shape and volume.

• Have no definite shape and no definite volume.

• Are incompressible and rigid.

• Are always visible and colorful.

Atom:

• The smallest fundamental building blocks of matter, made up of protons, neutrons & electrons.

• A type of molecule that contains only one element.

• A large structure made up of multiple cells.

• A particle that cannot be divided into smaller parts.

Weight

• The amount of gravitational force exerted on an object.

• The mass of an object measured in kilograms.

• The volume of an object measured in liters.

• The density of an object calculated as mass divided by volume.

Liquids

• They have a definite shape and volume.

• They have no definite shape, but they do have a definite volume.

• They have a definite shape, but no definite volume.

• They have no definite shape and no definite volume.

Boiling Point

• The temperature at which a liquid turns into a gas.

• The temperature at which a solid turns into a liquid.

• The temperature at which a gas condenses into a liquid.

• The temperature at which a liquid freezes into a solid.
