An otto cycle represents how an internal combustion engine

Question

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

3. Determine the energy input |Q h|

4. Determine the energy exhaust |Q c|

5. Determine the net output work for the engine (Weng.)

6. Calculate the thermal efficiency.
