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.
What else can I help you with?
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Is baking a potato endothermic or exothermic?
Endothermic because you have to put heat into the potato to bake it.
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
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?
Baking bread is an exothermic process. During baking, heat is applied to the dough causing chemical reactions to occur, such as the Maillard reaction and caramelization, which release heat energy in the form of steam and heat, resulting in the bread rising and forming a crust.
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.
Is freeezing endothermic or exothermic?
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
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 baking a potato endothermic or exothermic?
Endothermic because you have to put heat into the potato to bake it.
Does phenol red mixed with calcium chloride and baking soda turn out to be a exothermic or endothermic?
The reaction between phenol red, calcium chloride, and baking soda is endothermic. The mixture will absorb heat from its surroundings as it undergoes the reaction, causing the temperature of the mixture to decrease.
What is the opposite of exothermic?
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
Is sublimation a exothermic or endothermic?
endothermic
Is saponification exothermic or endothermic?
it is an endothermic
Is transpiration exothermic or endothermic?
endothermic
Is electrolysis exothermic or endothermic?
exothermic
Is bonding endothermic or exothermic?
exothermic
