Endotermisesti

Endotermisesti is a Swedish term that describes a process that absorbs heat from its surroundings. In chemistry and physics, this means that the process requires an input of energy, typically in the form of heat, to occur. The system undergoing the endotermic process experiences an increase in its internal energy, while the surroundings become cooler.

A common example of an endotermic process is melting ice. To transform solid ice into liquid water, heat energy must be absorbed from the environment. Similarly, many chemical reactions are endotermic. For instance, the decomposition of calcium carbonate into calcium oxide and carbon dioxide requires a significant amount of heat. Photosynthesis in plants is another well-known endotermic process, where light energy is absorbed to convert carbon dioxide and water into glucose and oxygen.

The enthalpy change for an endotermic process is positive, indicating that the system's enthalpy increases. This contrasts with exothermic processes, which release heat into their surroundings and have a negative enthalpy change. Understanding whether a process is endotermic or exothermic is crucial for predicting its behavior and for controlling its conditions in various scientific and industrial applications.
