Physical
it is not a change at all but putting pizza in the oven is a chemical change
chemical
Baking dough into bread is a chemical change because the heat causes chemical reactions to occur in the dough, leading to the formation of new substances such as carbon dioxide and water vapor, resulting in the transformation of the dough into bread.
Rolling cookie dough is not a chemical change; it is a physical change. During this process, the dough retains its chemical composition, and no new substances are formed. The ingredients remain the same, and only their physical shape and texture change as they are combined and shaped. Chemical changes would involve a transformation that alters the molecular structure, such as baking the dough.
Its a chemical change because its changing what it is (from dough to bread)
The transformation of dough into bread involves both physical and chemical changes. The physical changes include the expansion of the dough during baking due to the release of gases, while the chemical changes involve the reactions between proteins and starches in the dough leading to the formation of a stable bread structure.
The rising of dough is a physical change because it involves a change in appearance and volume without altering the chemical composition of the ingredients. On the other hand, it can also involve a chemical change as the yeast in the dough ferments and produces carbon dioxide gas, which helps the dough rise.
Carving a stone or molding a dough
Making dough is a combination of both physical and chemical reactions. Physical reactions occur when ingredients are mixed together to form a dough, while chemical reactions take place during the fermentation process when yeast converts sugars to gases.
Chemical, when it's cooked it can't be changed back to dough
It would be a chemical change/reaction.
Hey there, I am in grade eight, and out class is learning about that stuff too. I think that making dough from flour is a chemical and a physical change. But I will ask my teacher tomorrow and re-answer this question tomorrow or something
