    • Physical changes occur when a substance changes its state or properties without altering its chemical composition. For example, when water freezes, it undergoes a physical change from a liquid to a solid state. Similarly, when sand is compressed, it undergoes a physical change that increases its density. On the other hand, chemical changes involve the transformation of one substance into another through a chemical reaction. For instance, when wood is burned, it undergoes a chemical change that releases heat and light.

        How can I identify a physical or chemical change?

        However, there are also potential risks associated with not understanding the difference between physical and chemical changes, such as:

        To identify a physical or chemical change, observe the substance's state, properties, and behavior before and after the change. If the substance's chemical composition remains the same, it is likely a physical change. If the substance is transformed into a new substance through a chemical reaction, it is likely a chemical change.
