Document Summary
Thermodynamics: the science of energy and entropy; science that deals with heat and work and properties relating to heat and work. Macroscopic versus microscopic points of view: only investigate from macroscopic point of view; concerns overall or average effects of many molecules rather than x, y, z coordinates of each atom at all points in time. Energy: fundamental concept and difficult to define, energy: capability to produce an effect, stored within a system and transferred (eg. heat, in system with gas at certain pressure and temperature; from molecular point of view, forms of energy: Intermolecular potential energy: associated with forces between molecules. Molecular kinetic energy: associated with translational velocity of molecules. Intramolecular energy: associated with molecular and atomic structure and related forces. Specific volume and density: specific volume: volume per unit of mass, v, density: mass per unit of volume; reciprocal of specific volume, , intensive properties.
