Because it physically changes from a liquid state to a gaseous state.
you are physically changing the ice
Because physical state of water is changed from liquid to vapour.
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 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.
