endoenerginen

Endoenerginen is a term used in chemistry and physics to describe a process that requires energy input from its surroundings to occur. This is in contrast to exothermic processes, which release energy. An endoenergetic reaction, for example, will not proceed spontaneously without an external source of energy, such as heat, light, or electrical energy. The system undergoing the endoenergetic change absorbs energy, leading to an increase in its internal energy. The enthalpy change for an endoenergetic process is positive.

Examples of endoenergetic phenomena include photosynthesis, where plants absorb light energy to convert carbon dioxide and water into glucose and oxygen, and the melting of ice, which requires heat energy to break the bonds holding water molecules in a solid structure. In chemical reactions, if the products have a higher internal energy than the reactants, the reaction is endoenergetic and energy must be supplied. The term is often used interchangeably with endothermic, particularly in thermodynamics, though endoenergetic is a broader term that can encompass non-thermal energy inputs as well. Understanding whether a process is endoenergetic or exothermic is crucial for predicting its feasibility and for designing experiments or industrial processes.
