Chemical Engineering Thermodynamics Number of components (C), phase (P) and degrees of freedom (F) are related by Gibbs phase rule as P + F - C = 2 C = P - F + 2 F = C - P - 2 P = F - C - 2 P + F - C = 2 C = P - F + 2 F = C - P - 2 P = F - C - 2 ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics Law of corresponding states says that , two different gases behave similarly, if their reduced properties (i.e. P, V and T) are same 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) 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 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) The surface of separation (i. e. the meniscus) between liquid and vapour phase disappears at the critical temperature ANSWER DOWNLOAD EXAMIANS APP
