Here's a breakdown:
* Properties: Chemistry explores the physical and chemical properties of substances. This includes things like melting point, boiling point, density, reactivity, and how a substance interacts with other substances.
* Composition: Chemistry investigates the elements and compounds that make up a substance. It examines the ratios of these components and how they are arranged within the substance.
Chemistry is a vast and complex field, but its core focus is understanding the building blocks of matter and how they interact.
