Here's my problem: Measured data for pressure versus volume during the expansion of gases within the cylinder of an internal combustion engine are given in the table below. Data Point p (bar) V (cubic cm) 1 15 300 2 12 361 3 9 459 4 6 644 5 4 903 6 2 1608 A) Determine a value of n such that the data are fit by an equation of the form p*(V^n)=constant I got n=1.205559 and constant=14534.734 So p=14534.734/(V^1.205559) B) Evaluate analytically the work done by the gases, in KJ. I integrated 14534.734/(V^1.205559) with respect to V and evaluated with limits of 300 and 1608 (smallest and largest values for volume). I got 6389.453 *Question: What units should this be in? I know it's not in KJ, as the original data is in bars and cubic centimeters. How and where do I convert to get an answer in kJ? Any help would be greatly appreciated!
