The below table lists pressure and volume measurements for air in a cylindrical piston of an air compressor. The variables may be assumed related by: PV^k=C, where k and C are constants. CHE 255: Chemical Engineering Thermodynamics Due Friday, Jan 11th. Pressure (mmHg) Volume(cm3) 760. 48.3 1140 37.4 1520 31.3 2280 24.1 3040 20.0 3800 17.4 a.) First linearize the model equation and then determine the best fit values for k and C (include units and use correct significant figures). b.) What work is done by the compressor to the gas from the first measurement to the last? (I've plugged values into excel, but I do not know how to determine C, k, or W once I have the plot. Any help would be amazing.)
