CHM 114 Lecture Notes - Lecture 11: Thermodynamics, Energy Flux
Document Summary
Energy: capacity to do work and ability to produce change. Cannot see energy but may observe evidence that energy exists (converted or transferred from one form to another) Ek = k = *m*v 2 (m = mass of object) Energy associated with position of an object. Different forms of potential energy (simply has to do with position in space) Closed system : energy transfer but no mass transfer. Isolated system : neither energy nor mass transfer. Sum of all kinetic and potential energies of all components of system, we call it e. We seek to quantify change in internal energy of system, (delta e), when it. Internal energy, e transforms from some initial state to some final state. Measure energy flux into or out of system. When delta v > 0 transferring energy out of system.
