Understanding Physical and Chemical Properties of Substances

This article explores the fundamental differences between physical and chemical properties of substances. A physical property can be observed without altering the substance, while a physical change affects the appearance but not the chemical composition. Conversely, a chemical property is evident when a substance interacts with another, leading to a chemical change that creates a new substance. Additionally, we discuss important concepts such as mass, volume, and density, including the formula for density: Density = Mass/Volume.
