This process consists of three steps evaporation from the bulk liquid, expansion of the vapor from Pq to P and condensation into the pore. /Border [0 0 0] /Type /Annot /Type /Metadata 38 0 obj To learn more, view ourPrivacy Policy. endobj The correct equation and its derivation have been presented in the literature and can even be found in a minority of textbooks. endobj /Thumb 301 0 R 4 0 obj endobj /Annots [36 0 R 37 0 R 38 0 R 39 0 R 40 0 R 41 0 R 42 0 R 43 0 R 44 0 R] Fahrenheit and Kelvin are the two very commonly known and used scales for temperature. /D (cite.b1) endstream 32 0 obj /A 20 0 R 40 0 obj << /Resources 233 0 R Kelvin Plank Statement The production of a network, by a heat engine, that generates power and works in a thermodynamic cycle is impossible if it only exchanges heat at a fixed temperature.
