Physical

Chemical properties are properties that can be observed or measured when a substances undergoes a chemical change.

Physical properties are properties that can be observed without bringing a chemical change.

A chemical reaction needs to be conducted to show the property.

No chemical reaction is needed here.

Chemical properties are connected to chemical bonds of a substance.

Physical properties do not have such relationship.

It can be used to predict how substances react.

It is mostly used in identifying or describing the substance.

Chemical properties of a substance can include buoyancy, viscosity

compressibility, radioactivity, toxicity, flammability, heat of combustion, reactivity between chemicals, etc.

Examples of physical properties include:

molecular weight, boiling point, melting point, freezing point, volume, mass, length, density texture, color, odor, shape, solubility, etc.
