This article explores the fundamental concepts of physical and chemical properties and changes of matter. Examples such as magnetism, frying an egg, and rusting demonstrate the differences between physical changes, like sharpening a pencil, and chemical changes, such as burning wood and baking a cake. Readers will learn to identify signs of physical changes (like condensation) and chemical changes (like photosynthesis). The article also presents new examples of each type of change, enriching the understanding of these crucial scientific concepts.
