Question

differentiate between physical and chemical properties​

Answer 1

Substances have properties and characteristics by which we can identify and thus classify them. Two of the broad classifications of these would include the chemical and physical properties of a particular substance.

Physical properties can be observed or measured without changing the composition of matter. Physical properties are used to observe and describe matter.

Chemical properties are only observed during a chemical reaction and thus changing the substance's chemical composition.

Perhaps the best way to distinguish between the two is by examples. Examples of physical properties would include freezing, melting, and boiling points, density, mass, and volume. Examples of chemical properties include heat of combustion, reactivity with other chemicals, flammability, and types of bonds that will form

Answer 2

.A physical change in a substance doesn't change what the substance is....

.A chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed...
