which statement is correct?
Gasoline is injected into the cylinder of a car’s engine and compressed on the upstroke of the piston. The compression is well modeled as adiabatic. At the moment when the cylinder’s volume is at its lowest, but before the sparkplug ignites the mixture,
A. The ideal gas law applies, but will not apply after the ignition because it does not account for reactions such as combustion.
B. The temperature of the gas is higher than it was before the compression started.
C. You cannot plausibly write an energy balance using“the gas inside the cylinder” as a system, because of the very complex physical shape of the spark plug.
D. If a cubic equation of state describing the fluid at this point yields only one real number solution, this is an indication that the pressure of the gas is above the critical pressure.
E. None of these are correct.
