How is frying an egg a chemical change

Is the protonolysis reaction of sulfuric acid in aqueous solution an example of chemical change? Question What are the chemical changes of smores? See all questions in Physical and Chemical Changes. Impact of this question views around the world. You can reuse this answer Creative Commons License. Baking a cake is a chemical change because the baking powder or baking soda will undergo a chemical reaction. The heat helps baking powder or soda produce tiny bubbles of gas which makes the cake light and fluffy.

Frying an egg is a chemical reaction. It is an example of an endothermic reaction or one that takes in heat to make the reaction occur. In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not.

However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. Why is baking bread and 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.

As the cake is baked, the water evaporates. The evaporation is a physical change. So, in conclusion, you were right. The yeast in the dough releases CO2 gas, which is a chemical reaction because a new substance, the gas, is produced. A physical change that takes place when making pizza is when the cheese melts because a new substance is not created. Another physical change is the pizza increasing in size while it cooks.

Therefore, frying an egg is a chemical change because it results in the formation of new particles. Any substance that changes form, produces gas bubbles or changes color has undergone a chemical change. A chemical change cannot be reversed. For example, once an egg has been fried, it cannot ever go back to its original form. Once heat is applied, reactions occur, and most of the egg changes from liquid to solid. Cracking an egg shell is an example of a chemical change in matter.

In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. However in a chemical change, the kind of matter changes and at least one new substance with new properties is formed. When eggs are fried, they absorb heat energy. This breaks the weak chemical bonds that maintain the shape of the egg white proteins, causing them to uncurl.
