15.Calculate the slope of the line for your pressure vs. quantity graph (Excel will do this for you when you determine the line of best fit, please see the tutorial available on D2L or by your own online search). What properties does this number represent

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
