Exploring Physical and Chemical Properties

The video tutorial introduces physical and chemical properties, using examples like a cupcake and a piece of paper. Physical properties such as color, mass, volume, and density are discussed, which can be observed without changing the substance. Chemical properties like flammability, reactivity, and corrosiveness are explained, requiring a chemical reaction to be observed. A practical demonstration with paper highlights these concepts, emphasizing safety precautions.
