1 Physical and Chemical Properties

2 Physical and Chemical Changes https://ali1.acceleratelearning.com/scopes/201/elements/24 764 Explain – Content Connections

3 What is a Physical Property?

4 What are physical properties? Color Shape Density Volume Length Location Temperature Speed

5 What is a Chemical Property? Materials properties that become obvious during a chemical reaction

6 What are Chemical Properties? Reactivity with other chemicals pH Toxicity Flammability Types of chemical bonds that will form

7 What is a Physical Change? Affects the form of substance but not the chemical composition Can you name examples of physical changes?

8 What is a Chemical Change? A chemical change changes the arrangement of atoms – NOT THE ACTUAL ATOMS Key concept – Forms a NEW substance

9 How do we know a chemical change occurred? First question to ask yourself: “Is a new substance forming?” Other questions to ask: Is a gas forming? Are colors changing? Are different substances forming? If yes to any of these questions, indicates chemical change is taking place
