Physical VS Chemical Properties

Physical Property

Physical Property

can be observed and measured without changing the identity of the substance

Chemical Property

can be observed when substances react (combine) with another substance; as a result it becomes a new substance

Melting Point

Physical Property - temperature at which a substance changes from a solid to a liquid

Boiling Point

Physical Property - temperature at which a substance changes from a liquid to a gas

Density

Physical Property - the relationship between the mass of a material and its volume

Color

Physical Property - by itself this is not a significant identifier of a substance but does help identify based on appearance.

Mass

Physical Property - a measure of how much matter is present.

Volume

Physical Property - a measure of how much space an object takes up.

Flammability

Chemical Property - involves a substance reacting with oxygen quickly to produce light and heat

Rust

Chemical Property - involves a substance (iron) reacting slowly with oxygen

Conductivity

Physical Property - Ability to conduct heat or electricity

Texture

Physical Property - how the surface of a substance feels

Odor

Physical Property - how a substance affects the olfactory (smell) receptors

Magnetism

Physical Property - describes the attraction of a substance to a magnet. Most metals are will have this property.

Solubility

Physical Property - describes how easily a substance dissolves when mixed with another substance

Reactivity

Chemical Property - describes how a substance reacts when exposed to another substance

Solution

A mixture that forms when one substance dissolves another.

Solute

A substance that is dissolved in a solution.

Solvent

A liquid substance capable of dissolving other substances

ductility

Physical property-The ability to be pulled into thin wires without breaking

tarnish

Chemical change that results from surface reaction to air or moisture

thermal conductivity

Physical property-The ability of an object to transfer heat

hardness

Physical property-a measure of the ability of a mineral to resist scratching

luster

Physical property-shininess and able to reflect light

malleable

Physical Property-easy to shape or bend, can be pounded into sheets

corrosive

Chemical property- having the tendency to erode or eat away

pH

Chemical property-measure of acidity/alkalinity

radioactivity

Physical property-spontaneous emission of radiation by an unstable atomic nucleus

viscosity

Physical property-a liquid's resistance to flow

oxidizing

Chemical change that occurs when combining chemically with oxygen.

electrical conductivity

Physical property- how well a substance allows electricity to flow through it.

states of matter

the physical forms of matter, which include solid, liquid, and gas
