Get Physical And Chemical Changes And Properties Of Matter Worksheet Answer Key

Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.

If you change the way something looks, but haven't made a new substance, a physical change (P) has occurred. If the substance has been changes into another substance, a chemical change (C) has occurred.

Extensive properties vary with the amount of the substance and include mass, weight, and volume. Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.

Physical properties are characteristics that describe the objects themselves, without changing into other substances. An example of a physical property is color. Chemical properties are characteristics that describe an object's ability to change into a different substance.

For example, color, shape, mass, length, density, specific heat and odor are all examples of physical properties. A chemical property indicates how a substance reacts with something else. When a chemical property is observed, the original substance is changed into a different substance.

In a physical change, no new substance is formed. A chemical change is always accompanied by one or more new substance(s). Physical change is easily reversible i.e original substance can be recovered. Chemical changes are irreversible i.e. original substance cannot be recovered.
