Pure substances such as compounds and elements.
"Physical means" that is to say: No heating!
A lot of compounds decompose by simple heating, like making charcoal by heating wooden chunks.
a change in size, shape or the state of matter is a physical change. True for A+.
A pure substance.
An element or compound that cannot be physically separated is an atom. Atoms are the smallest unit of matter that retains the properties of an element and cannot be further broken down by physical means. Compounds, on the other hand, can be separated into their individual elements through chemical reactions.
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes

False. In a physical change, matter can change its shape without changing its chemical composition. Examples include melting, freezing, and dissolving.

no physical change does not change matter

A compound.
A pure substance contains only one kind of matter. It cannot be separated into other substances by physical means.
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.
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
