CHEM 1150 Lecture Notes - Lecture 6: Molecular Dynamics, Thermodynamics, Styrofoam
Document Summary
The study of molecular dynamics in chemical reactions. The study of energy and its transformations (heat and work). Energy associated with the random motion of atoms and molecules. Energy stored within the structural units of chemical substances. The capacity to do work or to transfer heat (electrical, thermal, chemical, etc. ) A limited, well defined part of the universe. Systems tend to attain the lowest energy possible. Ex: water on the floor, bikes on a hill. Processes that lower a systems energy tend to be spontaneous where processes that raise a systems energy tend to be non-spontaneous. Anything outside of the system being studied. A system that can exchange mass and energy with its surroundings. A system that cannot exchange mass but can exchange energy with its surroundings. A system that cannot exchange mass or energy with its surroundings. The change in momentum (p) per change in time.
