CHEM 14B Study Guide - Final Guide: Ideal Gas Law, Ideal Gas, Process Function
Document Summary
1. 1 learning objective: de ne thermodynamics deals with di erent forms of energy and conversions. Rst law- internal energy of an isolated system is constant. Open system: allow exchange of energy and matter. Closed system: exchange of only energy not matter walls: diathermal + moveable. Transferring work diathermal: allow heat transfer when theres a temp di erence. Adiabatic: doesnt allow heat transfer moveable: allow change in volume through transfer of energy through work. Rigid: prevents the transfer of work: state the properties of an ideal gas gas particles behave as hard spheres that occupy no space. No interaction between gas particles until a collision. At su ciently low pressure and high temperature, all gases are nearly ideal. Pv=nrt: calculate changes in ideal gas properties using the ideal gas law. Pv=nrt || p1v1/t1 = p2v2/t2: explain why the ideal gas law breaks down for real gases.
