Final answer:
The displacement of a 6 cylinder engine is the total volume of all cylinders; in a 2.40 L engine, each cylinder has 0.40 L. Work done by the engine can be calculated using the pressure and change in volume.
Step-by-step explanation:
The displacement of a 6 cylinder engine refers to the combined volume of all six cylinders within the engine. This is usually measured in liters or cubic centimeters (cc). To calculate the displacement for one cylinder, you would divide the total displacement by the number of cylinders. In our example with a total displacement of 2.40 liters, each cylinder would have a displacement of 0.40 liters, since 2.40 liters divided by 6 equals 0.40 liters.
When calculating work done by the engine, one must use the formula for work done by a gas, which is W = -PΔV, where W is work, P is pressure, and ΔV represents the change in volume. Assuming we have the volume change from the compression ratio and external pressure provided, we can calculate the work done in joules when the gas in one cylinder expands against the opposing pressure.
