Differentiating Physical and Chemical Properties

This video tutorial from MooMoo Math and Science explains the differences between physical and chemical properties. Physical properties describe the physical characteristics of a substance, such as luster, hardness, ductility, malleability, conductivity, density, solubility, melting point, and boiling point. Chemical properties, on the other hand, become evident after a chemical reaction and include flammability, radioactivity, oxidizing ability, corrosiveness, toxicity, explosiveness, and pH level. The video concludes with a reminder to practice kindness.

What is the main difference between physical and chemical properties?

• Physical properties describe physical characteristics, while chemical properties become evident after a chemical reaction.
