No
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.
Mashing potatoes is a physical change because it does not change the chemical or physical properties of the potatoes.
Making mashed potatoes involves a physical change because there is no new substance created during the process. The potatoes are still potatoes, just in a different form. The chemical composition of the potatoes remains the same before and after mashing.
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.
Physical, because it doesn't change chemical make up it just changes the appearance and texture
At a high temperature (during boiling or frying) the composition of potatoes is modified - a chemical change.
Mashing potatoes is a physical change because it does not change the chemical or physical properties of the potatoes.

its a chemical change beacuse it is irreversible :)
Chemical change.
Boiling is a physical change because the substance is changing from a liquid to a gas without changing its chemical composition.
Toasting bread, burning coal, frying an egg: chemical changes.Melting ice, boiling potatoes, buttering bread, dissolving sugar into water, boiling water: physical changes.
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
Mashing potatoes does not cause a chemical change because the composition of the potatoes remains the same. It is strictly a physical change, as the potatoes are being physically broken down into a new form but no new substances are being created.
