The phenol-water system has a upper critical solution temperature.

Which one of the following gases has the highest critical temperature ?

The system has unique solution if

The system has infinite solution , if

Assertion: A gas with higher critical temperature gets adsorbed to more extent than a gas with lower critical temperature. Reason: The easily liquefiable gases get adsorbed to more extent which have higher critical temperature.

The value of surface tension of a liquid at critical temperature

How the adsorption of a gas is related to the critical temperature

Gases possess characteristic critical temperature which depends upon the magnitude of intermolecualr forces between the gas particles, critical temperatures of ammonia and carbon dioxide are 405.5 K and 304.10 K respectively. Which of these gases will liquefy first when you start cooling from 500 K to their critical temperature ?

The system has no solution if ,

The critical temperature of a substance is
