Sure! Here are two examples of physical changes:
-
Melting Ice: When ice is heated, it changes from a solid state to a liquid state, forming water. This process is physical because the chemical composition of H2O remains the same, despite the change in physical form.
-
Dissolving Sugar in Water: When sugar is added to water and stirred, it dissolves, resulting in a sugar-water solution. This is a physical change because the individual sugar molecules disperse in the water, but the chemical structure of the sugar remains unchanged.
These examples illustrate how physical changes involve alterations in the state or appearance of a substance without affecting its chemical identity.
