Question: The adiabatic flame temperature of a fuel is the temperature achieved if the fuel is burned completely in a perfectly insulated container. You are performing

The adiabatic flame temperature of a fuel is the temperature achieved if the fuel is burned completely in a perfectly insulated container. You are performing an experiment to measure the adiabatic flame temperature of cyclopentane. You put 10.0mL of liquid cyclopentane into a well-insulated steel vessel with a volume of 11.2 Land pressurize the vessel with air to achieve a stoichiometric ratio of oxygen to cyclopentane. You then ignite the fuel, planning to record the final temperature. The vessel is equipped with a thermocouple and a pressure gauge.

(a) If room temperature is 27°C and barometric pressure is 1.00bar, what should the pressure gauge read prior to ignition?

(b) Suppose you discover after the combustion has been carried out that the thermocouple is not functioning properly. Use the final pressure gauge reading of 75.3bar to estimate the adiabatic flame temperature of cyclopentane. Do not assume ideal gas behavior.
