What are the properties of pure substances Brainly?
Pure substances are generally made up of only a single kind of atom or particle, has a definite structure, constant chemical composition and have a fixed boiling and melting poin-ts. Also, pure substances are very much homogeneous in mixture, they are often chemical elements or compounds.
What are the properties of pure substance appearance?
A pure substance has properties that are constant throughout the whole sample. This means that a pure substance will have a constant appearance, colour, density, melting point and boiling point throughout the sample.
What are properties of a substance?
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. A chemical property describes the ability of a substance to undergo a specific chemical change.
