EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed.

Detailed explanation-3: -The density of a substance remains constant and do not depend on the amount of substance. Also, the substance does not need to undergo any chemical reaction for identification of its density. Thus, density is considered to be as physical property.

Detailed explanation-4: -The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

Detailed explanation-5: -Density is an intensive property because there is a narrow range of densities across the samples. No matter what the initial mass was, densities were essentially the same. Since intensive properties do not depend on the amount of material, the data indicate that density is an intensive property of matter.
