Chemical Engineering Thermodynamics A closed system is cooled reversibly from 100°C to 50°C. If no work is done on the system Its internal energy (U) decreases and its entropy (S) increases U and S both decreases U decreases but S is constant U is constant but S decreases Its internal energy (U) decreases and its entropy (S) increases U and S both decreases U decreases but S is constant U is constant but S decreases ANSWER DOWNLOAD EXAMIANS APP
