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.

∙ 9y agoWhen baking a cake, heat is absorbed by the cake to cook. The absorption of heat makes the process endothermic.

∙ 13y agoit is exothermic, because heat is being added.

∙ 11y agoIm pretty sure it is a endothermic reaction. exothermic is the realsing of heat as to where endothermic is the capturing of heat. therefore baking cookies is an endothermic reaction

Is baking a potato endothermic or exothermic?
Endothermic because you have to put heat into the potato to bake it.
What are some physical endothermic phenomenons?
Some examples of exothermic reactions are melting ice cubes, water evaporation, and baking bread. An endothermic reaction occurs when heat is absorbed from the surrounding.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Is saponification exothermic or endothermic?
it is an endothermic
Is the process feeling cold exothermic or endothermic?
Exothermic/endothermic is a process not a feeling.
Is baking bread exothermic or endothermic?
endothermic
Is baking a potato endothermic or exothermic?
Endothermic because you have to put heat into the potato to bake it.
What are some physical endothermic phenomenons?
Some examples of exothermic reactions are melting ice cubes, water evaporation, and baking bread. An endothermic reaction occurs when heat is absorbed from the surrounding.
Is baking soda and vinegar an endothermic or exothermic reaction?
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
it results in a exothermic reaction
When clothes are drying is it an endothermic or an exothermic reaction?
The combustion is exothermic.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Contrast endothermic and exothermic reactions?
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.
Is baking soda and citric acid a endothermic or exothermic reaction?
It is endothermic. The heat of the water in the calorimeter decreases (giving you a -deltaH), which means that the system absorbed heat, making the reaction endothermic.
Is silicon endothermic or exothermic?
Silicon is an element - endothermic or exothermic is meaningless.
Is decomposition of phosphorus pentachloride endothermic or exothermic?
Exothermic reaction.
