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