The performance task related to this concept requires students to design, test, and modify a device that uses either an endothermic or exothermic process.EVELYN GRAYDeWitt Junior High School in DeWitt MichiganScience scope
Learn exothermic and endothermic reactions, their process, and the differences between them. See common endothermic vs exothermic examples.

Examples of Endothermic and Exothermic Processes Photosynthesisis an example of an endothermic chemical reaction. In this process, plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. This reaction requires 15MJ of energy (sunlight) for every kilogram of ...
Anexothermicprocess is one that gives off heat. This heat is transferred to the surroundings. Anendothermicprocess is one in which heat has to be supplied to the system from the surroundings. Athermoneutralprocess is one that neither requires heat from the surroundings nor gives off energy to th...
If the direction of a chemical equation is reversed, the arithmetic sign of its ΔH is changed (a process that is endothermic in one direction is exothermic in the opposite direction).Conceptually, ΔE (a measure of heat and work) and ΔH (a measure of heat at constant pressure) both ...

All processes can be classified into one of two categories: exothermic and endothermic. In an exothermic process, energy is released, while in an endothermic process, energy is stored. This section will specifically cover exothermic and endothermic chemical reactions, but almost any process can be ...
When going from a more ordered state to a less ordered state, the process is exothermic. When going from a less ordered state to more ordered state, the process is endothermic. References Chemistry LibreTexts: 11.4 Phase Changes HyperPhysics: Phase Changes ...
