Thermodynamic Pathways: an Example •Example 9.2. We take 2.00 mol of an ideal monatomic gas undergo the following: –Initial (State A): PA= 2.00 atm, VA= 10.0 L –Final (State B): PB= 1.00 atm, VB= 30.0 L • We’ll do this two ways:Path 1: Expansion then Cooling Path 2: Cooling then Expansion 2
Thermodynamic Jargon •When doing pathways, we usually keep one variable constant. The language used to indicate what is held constant is: –Isobaric: Constant Pressure –Isothermal: Constant Temperature –Isochoric: Constant Volume 3
