Is testing a physical or chemical property?

Answer 1

In Chemistry, knowledge of physical properties helps in the identification of elements and compounds. This information is useful for safety and storage purposes. Physical properties include density, boiling point, freezing point, viscosity, opacity, infrared spectrum, attraction and repulsion to magnets.

Answer 2

Safety is a good reason for knowing the chemical and physical properties of substances. For example, diluting acid by adding water can possibly cause acid burns to a person's skin or eyes because a large amount of heat is released when water is added to a strong acid, so much heat that the solution may boil very violently and splash acid out of the container, but slowly adding acid to water is a relatively safe procedure.

Answer 3

You don't need to know. He who knows may have more advantages than you.

Moreover, they are two interesting disciplines to study. When you start, it is very probable that you become keen on them.

Answer 4

Vague question begs vague answer:

So we know how matter reacts under varying conditions.

Answer 5

Because it will help to identify the substance and predict how it will act.

Answer 6

Testing is a process not a property. And this process may be chemical or physical.
