Provide an example of chemical and physical change

An example of a chemical change is the burning of wood. When wood burns, it undergoes a chemical reaction called combustion, where it reacts with oxygen to produce heat, light, and new substances such as water vapor and carbon dioxide.

An example of a physical change is the melting of ice. When ice is heated, it absorbs energy and its molecular structure is disrupted, causing it to transition from a solid state to a liquid state. This physical change does not alter the chemical composition of the substance.
