Endothermic because you have to put heat into the potato to bake it.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
it is an endothermic
Exothermic/endothermic is a process not a feeling.
Exothermic phenomenon
endothermic but don't know why? As AN crystals are formed the reaction is exothermic. Endothermic when it melts back with water. This is the reason AN is used in cold packs.
endothermic
Endothermic because you have to put heat into the potato to bake it.
This is a chemical change because once the substances are put together to form a gas it cannot be changed.
it results in a exothermic reaction
The combustion is exothermic.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
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.
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.
Silicon is an element - endothermic or exothermic is meaningless.
Exothermic reaction.
exothermic- because exothermic gives off heat and endothermic is cold
