Adding calcium to water results in a chemical change because the calcium and the water that react are combined to form a distinct new substance, calcium hydroxide, that did not exist in either the calcium or the water before their reaction.
Physical, you can reverse the process by evaporating or boiling the water
Adding calcium to water produces a gas (hydrogen H2) plus calcium hydroxide (Ca(OH)2). This is a chemical change.
Ca + H20 --> Ca(OH)2 + H2
The interaction between calcium and water is a chemical reaction.
