Endoergic

Endoergic is a term used in chemistry and physics to describe a process that absorbs energy from its surroundings. These processes are also known as endothermic reactions or endergonic reactions, depending on the specific context. In an endoergic process, the products of the reaction possess more energy than the reactants. This energy input is necessary for the reaction to occur and is typically supplied in the form of heat, light, or electrical energy.

A common example of an endoergic process is photosynthesis, where plants use light energy to convert carbon dioxide and water into glucose and oxygen. The formation of chemical bonds in glucose requires more energy than is released by breaking the bonds in the reactants. Another example is the melting of ice; heat energy must be absorbed by the ice to overcome the intermolecular forces holding the water molecules in a solid structure, transforming it into liquid water. In contrast to exoergic processes which release energy, endoergic processes are driven by an input of energy and result in an increase in the system's enthalpy. The overall energy balance of an endoergic process is positive, meaning energy is consumed rather than produced.
