EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Chemical properties are those properties that cannot be observed without changing matter to a new substance. Flammability and reactivity would be two examples of chemical properties.

Detailed explanation-3: -All matter has physical and chemical properties. Physical properties are characteristics that scientists can measure without changing the composition of the sample under study, such as mass, color, and volume (the amount of space occupied by a sample).

Detailed explanation-4: -Physical properties are those which can be measured without changing the identity of a substance. Color, hardness, volume, density, malleability, solubility, boiling, and melting points are some of the physical properties.

Detailed explanation-5: -Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
