Question

Color, hardness, solubility, mass, density, volume, and melting point are all examples of what type of property of substances?

Answer 1

Color, hardness, solubility, mass, density, volume, and melting point are all examples of physical properties of substances. This type of properties are those that can be measured or observed with a process that do not involve changing the composition and identity of the sample. These properties are used to describe a sample. The techniques and methods involved in measuring these properties only involve physical changes. Further, these properties are classified into extensive and intensive properties. Extensive properties are those that do not depend on the amount of the sample while intensive properties are the properties that depend on the amount of the sample.

Answer 2

All of these properties are known as physical properties.

Physical properties are such that they are measured without changing the composition of the of the matter which is under consideration. For example, the melting point of a substance may be tested without changing its composition. The change is also reversed easily. Physical properties are used to describe and observe matter. The other type of properties are chemical properties, which require the composition of a substance to be changed for them to be measured.
