The top answer ("the temperature of the bread goes up and the temperature of its surrounding will go down") is a terrible answer because whether baking bread is endothermic or exothermic depends on whether the chemical reactions that take place in the bread release energy or bind energy. That has absolutely nothing to do with the bread getting hot in the oven. Even a brick gets hot inside an oven yet there are no chemical processes occurring.
Because the temperature of the bread goes up and the temperature of its surrounding will go down
Baking bread is considered an endothermic reaction because it takes on the heat from its surroundings. Other examples include melting ice, and cooking an egg.
The word endothermic means the process of putting heat in.
Endo=into +thermo=heat +ic=process. So baking a cake requires that you put heat into it.
Baking a cake, burning paper, photosynthesis.
no it is not, it is a chemical and irreversible change,
Exothermic reactions release energy, it often produces an increase in temperature, and in this reaction, the bonds energies of the reactants are less then the energies of the products (meaning it is greater when it is on the reactant side).
Yes, some cake recipes call for baking soda as an ingredient.
cakes with baking soda and cakes without are the same.
Yes because endothermic is absorbing heat and a cake absorbs heat in order to make it hot. millemat001
Sounds like a homework question. We know that in an exothermic reaction, heat is taken out of the system and given to the surroundings. Whereas in an endothermic reaction, heat is pulled from the surroundings into the system. I am assuming you are thinking of the cookies as the system. So in this case, energy--in the form of heat--is being taken out of the oven and being put into the cookies. The cookies, using the energy increase in temperature, which bakes the cookies, creating the tasty little morsels of joy that cookies are.
An endothermic reaction is one which requires the continuous input of energy. Although some reactions require energy to start them off, e.g. combustion of wood, they will then continue to react and will emit energy, mainly in the form of heat, in an exothermic reaction. Baking a cake requires a continuous source of energy (i.e. the heat from an oven). If you turn the oven off, the cake will not continue cooking by itself. It is therefore endothermic.
Its where heat is taken in in a reaction eg making a cake is an endothermic reaction as heat is taken in to start it ;)
A cake produces a permanant colour change and a slight change in weight after baking. That means, It's a chemical reaction.
Baking powder is not a gas, but it does make a cake rise by releasing carbon dioxide into the batter through chemical reaction.
Yes, because baking involve chemical changes.
Baking a cake
Baking is a chemical reaction for a few reasons. First off, heat is being applied to change a substance (cake mix / batter) into another substance (baked cake). Reactions occur such as water and moisture turning to steam as a result of the heat, and ingredients like water and baking soda / powder react to create a fluffy cake.
It is a reaction to the baking soda.
Baking.
