Is bread dough rising a chemical or physical change?
Consequently, is bread baking a physical or chemical change?
Answer and Explanation: Baking bread is a chemical reaction. To bake a loaf of bread, many ingredients must be mixed together and heat must be added.
Likewise, what is the chemical reaction in bread? In bread making (or special yeasted cakes), the yeast organisms expel carbon dioxide as they feed off of sugars. As the dough rises and proofs, carbon dioxide is formed; this is why the dough volume increases. The carbon dioxide expands and moves as the bread dough warms and bakes in the oven. The bread rises and sets.
Besides, is bread rising a physical property?
The alcohol is what gives the bread its typical baked bread taste. The carbon dioxide expands as the dough is warmed, and causes the dough to rise. Accordingly I would say, yeast generating carbon dioxide is a chemical reaction. The rising of the bread is a physical change caused by gas expansion.
Why is baking bread an example of a chemical change?
Heating up the bread causes the dough to rise because of the heat. This is a chemical change because it is a transition from Mercury Oxide to Mercury and Oxygen.
