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

Answer : Option A
Explanation :
Law of corresponding states : at same reduced properties all the gases behaves similarly. This is the statement of corresponding states and the reduced property is defined as the state variables of a fluid scaled by the state properties at its critical point.
