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.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Endothermic because you have to put heat into the potato to bake it.
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
it is an endothermic
Exothermic/endothermic is a process not a feeling.
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.
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
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.
Endothermic because you have to put heat into the potato to bake it.
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.
The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.
