Physical Properties/Changes and Chemical Properties/Changes
One example of a physical change would be ripping paper. Lemonade made of powder is also a physical change because when you mix the powder with water, not all of the powder is dissolved and so the water is water and the powder is powder. Another example would be crushing a can.
An example of a chemical change would be digesting food. And since most chemical changes happens due to heat, baking and cooking are also examples of a chemical change. The four indicators of a chemical change would be: a change in temperature, a change in color, a formation of precipitate, and a production of a gas.
