The gas law for a fixed mass http://webwork2.asu.edu/webwork2_fil...ddbff75931.png of an ideal gas at absolute temperature http://webwork2.asu.edu/webwork2_fil...1e90188431.png, pressure http://webwork2.asu.edu/webwork2_fil...8d5ec3a3b1.png, and volume http://webwork2.asu.edu/webwork2_fil...850f274371.png is http://webwork2.asu.edu/webwork2_fil...fafeeeeda1.png, where http://webwork2.asu.edu/webwork2_fil...88af8355a1.png is the gas constant. Find the partial derivatives
