Unformatted text preview: a 1/volume value of 0 (mL). The mathematical relationship between pressure and volume is based off of the combined gas law. To maintain a constant pressure, one must change the pressure or volume in such a way that it is still proportionately equal. Example PV/T = PV/T 1atm(1L)/298K = 2atm(.5L)/298K P = 0.308(T) + 10.66 This line will not pass through the origin. Its yintercept will be at (0,10.66). The slope of the line is .308 kPa per degree K, which can be calculated by dividing the Pressure by ∆ Temperature over the same interval. ∆ P = 0.308(T) + 10.6610.66 = 0.308(T)34.61K = the temperature at which P = 0 Pressure (kPa) Temperature (K) 95.16 274.74 100.07 289.95 101.04 293.15 105.78 308.15 110.05 323.15...
