Document Summary

Chapter 3: quantum theory and the electronic structure of atoms. Kinetic energy: energy that results from motion; 0. 5mv^2. Thermal energy: energy associated with the random motion of atoms and molecules. Potential energy: energy possessed by an object by virtue of its position. Chemical energy: energy stored within the structural units of chemical substances. Structural units: may be ions or molecules. Electrostatic energy: potential energy that results from the interaction of charged particles. Equation: e = (q1q2)/d, where q represents the different charges of the particles and d represents the distance between them. Law of conservation of energy: when energy of one form disappears, the same amount of energy must appear in another form or forms (energy = capacity to do work) Si unit for energy is the joule (j) = kg*(m^2/s^2) Joule: amount of energy exerted when a force of 1 newton (n) is applied over a distance of one meter.
