1. Fill in the following table with the appropriate equations or information. If any values are zero, explicitly say so. Some cells have been provided for you.

Process:	Constant:	Ideal Gas Relation	W (J)	Q (J)	A???U
Adiabatic					A???U = W
Adiabatic Free Expansion
Isobaric	pressure			Q = A???U - W
Isovolumetric			W = 0
Isothermal		P1V1 = P2V2

2. An Otto cycle represents how an internal combustion engine works. The compression ratio of the Otto cycle shown is VA/VB = 8.00. At the beginning (state A) of the compression process, 500 cm3 of gas is at 100 kPa and 20.0^oC. At the beginning of the adiabatic expansion, the temperature is TC = 750^oC. Model this system as acting on a diatomic ideal gas. Fill in the following two tables

	P	V	K
A
B
C
D

	W	Q	A???U
A -> B
B -> C
C -> D
D -> A
Whole Cycle
