Answer:    Composition of matter

Explanation:   All substances, compounds, elements, have different physical and chemical properties, which can be altered by changes in the physical and chemical conditions in which these substances are found. For example, a boiling point of a substrate may be achieved, or by cooling it may lead to a freezing point. However, in any of these cases, the composition of matter does not change.

The question is incomplete, the complete question is;

Which property of a substance is not altered by a physical change?

A) shape

B) density

C) composition

D) temperature

The correct answer is option C: composition

Matter can undergo two kinds of changes;

  • Physical change
  • Chemical change

Chemical change leads to the formation of new substances. A precipitate may also appear. A chemical change may involve absorption or evolution of heat. Since a new substance is formed after a chemical change, then the "Composition" of the substance has been changed.

A physical change does not lead to the formation of new substance. The substance retains its composition after a physical change.
