Burning wood is an example of a chemical change.
To determine which option is an example of a chemical change, you need to understand the difference between physical changes and chemical changes.
A physical change is a change that only affects the physical properties of a substance, such as its shape, size, or state of matter, without altering its chemical composition. Examples of physical changes include folding paper and stretching a rubber band. These changes can be easily reversed.
On the other hand, a chemical change is a change that affects the chemical composition of a substance, resulting in the formation of one or more new substances. Examples of chemical changes include chopping vegetables and burning wood. These changes cannot be easily reversed because the substances involved undergo a chemical transformation.
From the given options, burning wood is the example of a chemical change. When wood is burned, it undergoes a chemical reaction with oxygen in the air, resulting in the formation of new substances like ash and smoke. This change is irreversible, and the original wood is converted into different substances.
Therefore, the correct option is option e) burning wood.
