Exploring Physical and Chemical Properties of Matter

Mr. Cazy introduces a chemistry lesson on the properties of matter, focusing on physical and chemical properties and changes. Physical properties involve no new substances, while chemical properties result in new substances. Examples and characteristics of each type are discussed, emphasizing the importance of understanding these concepts for future lessons on phase changes and thermodynamics. The lesson concludes with a recap and resources for further learning.
