Explanation:

Chemical change is defined as the change in which a change is the chemical composition takes place resulting in the formation of new substance. It is usually an irreversible reaction.

Physical change is defined as the change in which shape and size of a substance changes, There is no change in the composition of the substance as no new substance is forming. It is usually an reversible reaction.

From the above definition,

1. Dissolving salt into water: It is a physical change because the crystals of the salt changes.

2. Burning wood: It is a chemical change because carbon dioxide and water is forming as the products.

3. Digesting food: It is a chemical change because food is being broken down into simpler organic molecules.

4. Tearing paper: It is a physical change because only the shape of the paper is changing.

5. Drying clothing: It is a physical process because water is getting evaporated and its physical state is changing from water to vapor.

6. Growing plants: It is a physical process because only shape of the plant is changing.
