CHEM 001A Lecture Notes - Lecture 14: Kinetic Energy, Thermal Energy, Thermal Equilibrium
Document Summary
Work : moving matter against an external force. Potential energy (pe) : the energy stored in an object because of its position, Two types of energy composition, or condition. Kinetic energy (ke) : the energy due to motion of the object. State function : depends only on the difference between initial and final state of the system and not how it achieved that state. Total energy = pe + ke = mgh + mv 2. Energy can be neither created nor destroyed. Energy can be converted from one form to another. Thermal energy : kinetic energy of atoms, ions, and molecules. Mass, velocity of the particle (ke = mv 2 ) Thermodynamics : the study of energy and its transformations. Thermochemistry : the study of the relationship between chemical reactions and. Heat : the energy transferred between objects due to a difference in temperature. System : the part of the universe that is the focus of a thermochemical study.
