If a substance can be separated by physical means and is not the same throughout, it is classified as a heterogeneous mixture. In such mixtures, the individual components can be distinguished and separated, often having different compositions or properties. Examples include salad, sand and iron filings, or oil and water, where the components retain their distinct identities.
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.
If a substance can be physically separated into its components, it is a mixture, not a pure substance. A pure substance consists of only one type of particle and cannot be separated into other substances by physical means.
A pure substance.
Yes, all homogeneous matter can be classified as a pure substance because it has a uniform composition throughout. This means that all samples of the matter have the same properties and composition, making it a pure substance.
A compound can be separated into two or more substances through chemical reactions. Physical mixtures, such as an alloy or a solution, can also be separated into their individual components through physical means like filtration or distillation.

It wouldn't be a single substance, it would be a mixture.
A substance can be categorized into several categories. If a substance cannot be separated through physical means (e.g., distillation, magnetism) it is a pure substance. If a substance can be separated through physical means, it is a mixture. If a mixture is uniform throughout, it is a homogenous mixture, like saltwater. If it is not (i.e., there are different parts to it, like a can of soda), it is a heterogeneous mixture. If a pure substance can be separated through chemical means, it is a compound, like glucose, which is made of carbon, oxygen, and hydrogen. If a substance cannot be separated by chemical means, it is an element, like oxygen, which is made of just oxygen. A substance can be in multiple categories.

A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.
