A reaction that gives off energy
An endothermic reaction is one that consumes heat.
Exothermic.
When amino acids combine to form proteins or polypeptides a condensation reaction occurs. The carboxyl group of one molecule reacts with the amine group of the other molecule. One molecule of water is released and this results in C(O)NH, or a peptide bond. Condensation is the reaction: the opposite process is termed Hydrolysis.
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
condensation is when your water/beverage bottle is cold and the liquid that comes off the side is condensation.
During condensation, steam gives off heat energy to its surroundings. This heat energy is released as the steam cools down and transforms back into liquid water.
Endothermic reactions increase their enthalpy by absorbing heat
