Chemical Engineering Thermodynamics Law of corresponding states says that No gas can be liquified above the critical temperature, howsoever high the pressure may be , 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 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 , 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 The molar heat of energy of gas at constant volume should be nearly constant (about 3 calories) ANSWER DOWNLOAD EXAMIANS APP
