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 is constant but S decreases Its internal energy (U) decreases and its entropy (S) increases U decreases but S is constant U and S both decreases U is constant but S decreases Its internal energy (U) decreases and its entropy (S) increases U decreases but S is constant ANSWER DOWNLOAD EXAMIANS APP
