검증된 단계별 안내1
Understand that physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity.
Recognize that mass, volume, and shape are physical properties but are not unique to a pure substance because they can vary depending on the amount or form of the sample.
Learn that melting point is a physical property that is characteristic and unique for each pure substance because it occurs at a specific temperature under standard conditions.
Use the melting point as an identifying property because pure substances have a sharp and reproducible melting point, whereas mixtures melt over a range of temperatures.
Conclude that among the options given, melting point is the physical property typically unique to each pure substance and useful for identification.
