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.
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.
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.

New substances are not being formed. The water is simply changing from one state (liquid) to another (gas)
Boiling water is a physical change because you aren't changing the chemical components of water, just forcing the molecules away from each other.
During boiling the chemical formula of water is not changed.
I don’t know
This involves a change of state of the water. Before, during, and after the boiling, it remains water. So, since the substance doesn't change its character, the boiling of water is a physical change.
Boiling water is physical change.
Boiling of water is a physical process, a change of phase.
Boiling is a physical process, a change of phase.
Boiling and evaporation are physical changes.

Boiling is a physical change.
Boiling point is a physical property. This is because when an element boils, it changes its state of matter, which is a physical change.
Boiling is a physical phenomenon, a change of phase.
Boiling water is a physical change because it does not change the chemical composition of the water.
Boiling water is physical change.
vaporization
Boiling of water is a physical process, a change of phase.
Physical change because the water molecules stay unchanged during boiling, also the germination phase helps this be proved correct=)
Boiling is a physical process, a change of phase.
Boiling and evaporation are physical changes.
When water boils, it is a physical change.
