Frequent question: Is baking a cake an exothermic reaction?

Is baking a cake endothermic or exothermic and why?

Baking a cake is endothermic chemical reaction. The heat helps produces bubbles in the cake that make it light and fluffy.

Is frying an egg endothermic or exothermic?

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.

Is melting endothermic or exothermic?

However, it can be used for both the melting and the solidification processes as long as you keep in mind that melting is always endothermic (so ΔH will be positive), while solidification is always exothermic (so ΔH will be negative).

What two ingredients tenderize baked?

In general, baking ingredients can be divided into two types, “tougheners / strengtheners” (flour, eggs) and “tenderizers / weakeners” (fat, sugar), sometimes overlapping.

How does batter turn into cake?

1) When heated and mixed with water, starches present in the flour will undergo a process called gelatinization in which water is absorbed in the structure. This will cause the batter to ‘set’ from a liquid into a solid.

Is burning a chemical change?

The process of burning (as opposed to evaporating) is a chemical reaction, a chemical change. The wax molecules are undergoing a chemical change; they are changing into different molecules by reacting with a substance in the air.

Is baking a cake reversible or irreversible?

Like many natural processes in science, baking a cake is an irreversible process; once the ingredients are mixed up and baked, there is no going back. We cannot disentangle and separate the various ingredients from each other.

Is mixing sand and sugar reversible?

Answer: reversible change is the answer .
