shape and volume
One characteristic property to identify similar liquids apart is their boiling point. Liquids with different boiling points can be easily distinguished by observing when they change from liquid to gas state. Additionally, density and refractive index can also be used to differentiate between similar liquids.
The viscosity of a substance will change with both temperature and pressure. For liquids the changes induced by a change in temperature are usually more readily observed than the changes from pressure because liquids are only slightly compressible with pressure. In gasses, the changes in viscosity with pressure are much more easily demonstrated because gases are, almost by definition, quite compressible so that the density can be easily changed by either changes in pressure or changes in temperature.
Gases have the property of indefinite shape and volume, as they expand to fill any container. They also have low density compared to liquids and solids. Gases can be compressed and expand easily when heated.
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
A substance that changes its form easily is typically referred to as a "fluid." Fluids can be further classified as liquids or gases, depending on their specific properties. These substances do not have a fixed shape or volume and can flow easily.
not easily compressed definite mass i think
False. Solids have a definite shape and volume, meaning they resist changes in volume under normal conditions. While they can undergo slight changes in volume due to temperature variations or pressure, these changes are typically minimal compared to liquids and gases.
Yes, the ability to melt easily is a physical property of a substance, not a chemical property. Chemical properties describe how a substance reacts with other substances or undergoes chemical changes.
Yes. Liquids can change their shape as they do not have a definite shape and size. They take the shape of a container or jar for example.
Physical - because melting isn't a change in it's chemical structure, it has just changed its physical state of matter. Generally (but not always) physical changes are reversible (can be taken back) but chemical ones cannot be reversed easily.
