Answer 1

A change from physical change into chemical change not sure hope this helps

Answer 2

Physical change

Step-by-step explanation:

Different types of changes take place. Two such changes are physical change and chemical change.

Physical change

This takes place when a substance changes from one state to another without changing the chemical composition. For example, water changes from liquid to solid (ice) when frozen. Thus, water has not changed its chemical properties. A physical change is reversible.

Thus, the melting of aluminium cans is a physical change.

Chemical change

This is a reaction that changes the original reactants to give different products. For example, burning coal gives ash, soot, carbon dioxide and water. Most chemical reactions are irreversible.
