In a cylinder of an automobile engine, immediately after combustion the gas is confined to a volume of 56.0cm^(3) and has an initial pressure of 2.90 imes 10^(6)Pa. The piston moves outward to a final volume of 300cm^(3), and the gas expands without energy transfer by heat. (Assume the gas in the engine is diatomic with gamma =1.40.)
(a) What is the final pressure of the gas (in kPa )?
Your response is off by a multiple of ten. kPa
(b) How much work is done by the gas in expanding (in J)?
J
(c) What If? If the engine operates in an ideal Otto cycle and 0.0125mol of fuel-air mixture is injected into the cylinder during the intake stroke, what are the temperatures (in K ) at points A,B,C, and D of the cycle as shown in the figure?

T_(B)=, imes K
T_(C)=, imes K
T_(D)=, imes K
