It depends on what is boiling. If you are boiling WATER, then it is NOT a chemical change, it is a physical change (change of state from liquid to gas).
If you are cooking food on the stove, a chemical change is occuring. That is, the chemical bonds within the food molecules are actually changing. One way you can tell that it is a chemical change is that you can't "uncook" food, but you can condense steam back into water.
It's a physical change because no chemical change has occurred in any series of fluids
Cooking is a chemical change in all situations.
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.

Boiling water is a physical change because it does not change the chemical composition of the water.

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.
Boiling is a physical phenomenon, a change of phase.
a physical becauseb it does not effect the chemical make up
