How does boiling water a physical change?

Answer 1

A physical change is when a substance undergoes a process whereby its physical features change but its chemical features stay the same.

A chemical change is when an object undergoes a process whereby its chemical composition changes.

The water leaving as steam has undergone a physical change (evaporation) from a liquid state to a gaseous one, but no chemical change has occurred because it is still H2O. By definition, any change in the state of matter is a physical change.

Answer 2

Because the actual checmical makeup of the water doesn't change. It is still H2O, it's just that the molecules are sped up and spread apart. In order to be a chemical change, the molecule itself would need to become a different one.

Answer 3

A physical change is a change that its form or appearance of matter changes but not its composition. Boiling water is a physical change because you only change the temperature but the matter is still water.

Answer 4

Boiling water is a physical change because it involves a change in the state of water from liquid to gas without altering the chemical composition of water molecules. The process of boiling only affects the intermolecular forces holding water molecules together, not the actual chemical bonds within the molecules.

Answer 5

New substances are not being formed. The water is simply changing from one state (liquid) to another (gas)

Answer 6

Boiling water is a physical change because you aren't changing the chemical components of water, just forcing the molecules away from each other.

Answer 7

During boiling the chemical formula of water is not changed.
