JCP321H5 Chapter Notes - Chapter 1: 3Dm, Elementary Charge, Real Gas
Document Summary
Thermochemistry - branch of science that describes the behaviour of matter and the transformation between different forms of energy on amacroscopic scale (measurement);only a few such variables needed to describe a system of interest. 1 molof gaseous water is described by three macroscopic variables, pressure, volume and temperature. One the microscopic scale by contrast refers to dimensions on order of the molecular size eg. h2o a dipolar triatomic molecule with a b. a at 104. 5 degrees. Statistical thermodynamics uses atomics/molecular properties to calculate macroscopic properties. System consists of all materials in the process involved in the process under study. Rest of the universe is referred to as the surroundings. 2 types of systems: open system a system that can exchange matter with surroundings eg. animal vs. plant cells, closed sytem a system that cannot exchange matter with surroundings as open systems. { both systems can exchange matter with surroundings} A system that can do neither is an isolated system.
