This is a physical change. Water can take on 3 forms, ice, gas, and liquid. These would be changes in state.
Tearing, scratching, crushing, change in state, are all physical changes.
Chemical changes must change the substance, not just the appearance.
(i.e. Burning fire into ashes, fireworks exploding...)
it is a phsical change
It is a physical change because the change is reversible.
Mixing lemonade powder into water is a chemical change. This is because the powder changes the water molecules and can not be taken out.
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
Chemical change: the composition of the initial reactants is changed. Ex.: thermal decomposition of calcium carbonate. Physical change: the composition is not changed during this transformation. Ex.: boiling of water.
It is both physical and chemical. Evaporation of water is a physical process, and reduction of water from clothing is also a chemical process.
Boiling water is a physical change because it does not change the chemical composition of the water.
Water boiling is a physical change and not a chemical reaction. In a physical reaction there is no new substance formed as is the case with chemical reactions. In boiling water there is no new substance produced.
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 and evaporation are physical changes.

It is a physical change.
Boiling is a physical change.
It is a physical change. All phase changes are physical, not chemical. The chemical composition of water does not change when it changes from a liquid to a gas, or for that matter, to a solid.
cold water heating up to its boiling point a physical change or a chemical change
Boiling is a physical phenomenon, a change of phase.
a physical becauseb it does not effect the chemical make up
