The contained chemical potential energy, thus releases as heat along with light energy that is generated simultaneously. On Earth this is 9.8 meters/seconds. Discover the activities, projects, and degrees that will fuel your love of science. Systems prefer a low potential energy and thus repel each other which increases the distance between them and lowers the potential energy. Do add them to our list, through the comments section below. ✦ The temperature determines the change in an object’s chemical energy i.e. In an endothermic reaction the opposite occurs. This is said to be a good approximation of the chemical potential. She has taught science courses at the high school, college, and graduate levels. Here, there is conservation of energy (i.e.

On lifting an object from its rest position, there will be stored energy. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739.

It is called potential because it has the potential to be converted into other forms of energy, such as kinetic energy.

For instance, gravitational potential energy is the energy that things have if they are high up. In thermodynamics, chemical potential of a species is energy that can be absorbed or released due to a change of the particle number of the given species, e.g. The LibreTexts libraries are Powered by MindTouch® and are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. Thus, you must have realized that chemical potential energy refers to the energy stored in a substance owing to the chemical bonds present in it. This website uses cookies to improve your experience while you navigate through the website. A 200 gram weight is placed on top of a shelf with a potential energy of 5 J. Return to top of page. Adopted or used LibreTexts for your course? This stored energy is released, when the substance undergoes a chemical reaction and the bonds are broken. Potential energy is usually defined in … That is, stronger bonds have low chemical potential energy. This potential energy becomes kinetic energy as the ball accelerates towards the ground. Necessary cookies are absolutely essential for the website to function properly. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is called nuclear potential energy; work of intermolecular forces is called intermolecular potential energy.
