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

Chemical Engineering Thermodynamics Law of corresponding states says that No gas can be liquified above the critical temperature, howsoever high the pressure may be The molar heat of energy of gas at constant volume should be nearly constant (about 3 calories) , two different gases behave similarly, if their reduced properties (i.e. P, V and T) are same The surface of separation (i. e. the meniscus) between liquid and vapour phase disappears at the critical temperature No gas can be liquified above the critical temperature, howsoever high the pressure may be The molar heat of energy of gas at constant volume should be nearly constant (about 3 calories) , two different gases behave similarly, if their reduced properties (i.e. P, V and T) are same The surface of separation (i. e. the meniscus) between liquid and vapour phase disappears at the critical temperature ANSWER DOWNLOAD EXAMIANS APP
