Exploring Physical vs 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, such as tearing paper, while chemical properties result in new substances, like burning paper. The lesson emphasizes understanding these concepts as foundational to chemistry, with examples and a recap of key ideas. Additional resources and contact information are provided for further learning.

What is the primary focus of chemistry as discussed in the video?

• The periodic table

• Laboratory experiments

• The study of elements
