Chemical Engineering Thermodynamics A closed system is cooled reversibly from 100°C to 50°C. If no work is done on the system U and S both decreases U decreases but S is constant Its internal energy (U) decreases and its entropy (S) increases U is constant but S decreases U and S both decreases U decreases but S is constant Its internal energy (U) decreases and its entropy (S) increases U is constant but S decreases ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics At 60° C, vapour pressure of methanol and water are 84.562 kPa and 19.953 kPa respectively. An aqueous solution of methanol at 60° C exerts a pressure of 39.223 kPa; the liquid phase and vapour phase mole fractions of methanol are 0.1686 and 0.5714 respectively.
