As you bake a cake, you are producing an endothermic chemical reaction that changes ooey-gooey batter into a fluffy, delicious treat! A few things can happen when you bake a cake.
Is baking a cake an exothermic reaction?
There are two types of heat changing reactions when you bake a cake. Exothermic is when energy energy is released. Endothermic is when energy is absorbed. Baking a cake is endothermic chemical reaction.
What is baking a cake?
Cake is a form of sweet food made from flour, sugar, and other ingredients, that is usually baked. … The most commonly used cake ingredients include flour, sugar, eggs, butter or oil or margarine, a liquid, and leavening agents, such as baking soda or baking powder.
Is baking exothermic or endothermic reaction?
In addition to smelling delicious, baking bread is an endothermic example. The flour, yeast, and other ingredients used in creating the dough are heated. They absorb the heat making chemical reactions happen.
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 Baking Works.
|Tougheners / Strengtheners||Tenderizers / Weakeners|
|egg whites||egg yolks|
Is frying an egg endothermic or exothermic?
Cooking of an egg is an endothermic reaction. Cooking is the art , technology , science and craft of using heat to prepare food for consumption. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. In this case heat energy is absorbed from the pan to the egg.
Do all cakes need baking powder?
Baking Without Baking Powder
While modern pound cake recipes do include baking powder, if you mix the basic ingredients in a pound cake correctly you can bake a delicious cake without any chemical leavening at all. Mixing the cake correctly is essential, since the eggs are the sole leavening agent.
How long does cake take to bake?
Bake until the cakes are lightly golden on top and a toothpick inserted into the middle comes out clean, 30 to 35 minutes. Transfer to racks and let cool 10 minutes, then run a knife around the edge of the pans and turn the cakes out onto the racks to cool completely.

Is Melting endothermic or exothermic?
This means that melting, vaporization and sublimation are all endothermic processes. They require the addition of energy or heat. The reverse processes (freezing, condensation and deposition) are all exothermic processes. This means that they release heat.
Is Melting ice endothermic or exothermic?
In order to melt the ice cube, heat is required, so the process is endothermic. Endothermic reactionIn an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction.
Is burning a candle endothermic or exothermic?
The wax is burning and turning into carbon dioxide and water. In the process, it gives off heat (and light). Giving off of heat makes it exothermic (heat exits the reaction… exothermic).
What different ingredients do in baking?
Each ingredient has a job to do. Flour provides the structure; baking powder and baking soda give the cake its airiness; eggs bind the ingredients; butter and oil tenderize; sugar sweetens; and milk or water provides moisture.
What does milk do in a cake?
Milk is used in baked products to improve texture and mouthfeel. The protein in milk also gives a soft crumb structure in cakes, and contributes to the moisture, colour and flavour of a baked product.
What does milk do in a cake recipe?
The protein in milk softens, contributes moisture, and adds colour and flavour to baked goods. It’s a double-whammy in terms of function, as it gives the dough or batter strength and structure, as well as adds tenderness, flavour and moisture.
