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 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)

, two different gases behave similarly, if their reduced properties (i.e. P, V and T) are same
