Question

Explain the differences between physical and chemical properties

A) Physical properties involve changes in composition, while chemical properties involve changes in appearance.
B) Physical properties are observable characteristics, while chemical properties describe the behavior of substances.
C) Physical and chemical properties are interchangeable terms.
D) Both physical and chemical properties refer to changes in substance identity.

Answer 1

Physical properties are observable characteristics of a substance, while chemical properties describe the behavior of substances.

Step-by-step explanation:

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Examples of physical properties include color, density, hardness, and melting and boiling points. On the other hand, a chemical property describes the ability of a substance to undergo a specific chemical change. It relates to the behavior of substances and includes properties such as flammability or reactivity.

The main difference between physical and chemical properties is that physical properties are observable characteristics of a substance, whereas chemical properties describe the behavior of substances. Physical properties can be measured or observed without changing the substance's identity, while chemical properties are revealed through chemical changes that result in the formation of different substances with new properties.
