Document Summary

Thermochemistry study of heat absorbed or released during chemical reactions and/or physical changes: part of thermodynamics. Thermodynamics study of heat and its interconversions with other types of energy. Energy the capacity to do work: possessed by an object or a set of objects. Work the result of a force acting through a distance: transfer of energy from one object to another, the way objects exchange energy. Heat the flow of energy caused by a temperature difference: the way objects exchange energy. Kinetic energy the energy of motion of an object. Thermal energy the energy associated with the temperature of an object: a type of kinetic energy because it arises from the motion of atoms or molecules within a substance. Potential energy the energy associated with the position or composition of an object. Chemical energy the energy associated with the relative positions of electron and nuclei in atoms and molecules: also a form of potential energy.
