Answer 2

Lead is melted into a liquid to form pellets. - This scenario is an example of a physical change.

• A change is called a physical change when the change is limited only to change in physical condition only. In a physical change, the chemical composition does not change at all.
• When lead is melted to form pellets, its state changes from solid to liquid. But, the chemical composition still remains the same, hence this is a physical change.
• When wood is burned to ashes, a chemical change occurs.
• When metal is rusted, it is oxidized changing its chemical composition.
• When sugar is changed into water and carbon dioxide, new products are formed. Hence, this is a chemical change.
