Physical.
Boiling is a physical change, not a chemical change. It does not alter the chemical composition of the substance. It is simply a phase change from liquid to gas.
Boiling potatoes is a physical change, not a chemical change. The heat causes the starch in the potatoes to gelatinize and the cells to rupture, but the chemical composition of the potatoes remains the same.
Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.
When a kettle is boiling you are able to see the chemical reaction, from the stem leaving the kettle.
Yes, boiling alcohol and considering the vapor is a physical change as it does not alter the chemical structure of the alcohol molecules. The alcohol vapor can be condensed back into liquid alcohol without undergoing a chemical change.

Chemical change.
Boiling is a physical change because the substance is changing from a liquid to a gas without changing its chemical composition.
Boiling is a physical change.
No, hard-boiling an egg is a chemical change. By cooking the egg you change its chemical composition.
no, boiling is a physical change
Cooking is a chemical process.
Boiling is a physical change, not chemical.
Boiling is a physical phenomenon.
It is a physical change because the apple is still an apple and nothing changed the composition of what's in the apple.
Boiling potatoes is a physical change, not a chemical change. The heat causes the starch in the potatoes to gelatinize and the cells to rupture, but the chemical composition of the potatoes remains the same.
