A material’s mass is given by the equation, m = 32P0.02/T0.5, where T is in Kelvin, m is in Kg and P is in mm Hg, what is the mass of material at 127oC, use A = 10, B = 6 X 103 and C = 0?
Explanation: ln p* = A – B/(C + T) = 10 – 6 X 103/(400) = -5, => p = 0.0067 mm Hg, => m = 32*(0.0067)0.02/4000.5 = 1.44 Kg.
