Different Forms of Energy - ANSWER-Thermal, mechanical, kinetic, potential, electric, magnetic, chemical, and nuclear Macroscopic Energy - ANSWER-The forms of energy a system possesses as a whole with respect to an outside reference frame, such as kinetic or potential energies Microscopic Energy - ANSWER-The forms of energy related to the molecular structure of a system and to the degree of molecular activity, independent of outside reference frames. Internal Energy - ANSWER-Sum of all microscopic forms of energy Kinetic Energy - ANSWER-Energy that a system possesses as a *result of its motion* relative to some outside reference frame Potential energy - ANSWER-Energy that a system possesses *as a result of its elevation* in a gravitational field Types of Internal Energy - ANSWER-Sensible, Latent, chemical, and nuclear energy Types of microscopic energies that make up sensible energy - ANSWER-Molecular translation, Molecular rotation, Molecular vibration, Electron spin, Nuclear spin, and Electron translation. Sensible Energy - ANSWER-The portion of internal energy of a system associated with the kinetic energies of the molecules Latent Energy - ANSWER-The internal energy associated with the phase of a system Chemical Energy - ANSWER-The internal energy associated with the atomic bonds in a molecule Nuclear Energy - ANSWER-The tremendous amount of energy associated with the strong bonds within the nucleus of the atom itself. Static forms of Energy - ANSWER-The total energy that is contained or stored in a system
