Critical temperature (T_(C )) will be maximum for the following gas ?

At which of the following conditions can a gas be liquified? T_(c) and P_(c) are critical temperature and pressure.

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.

Statement-1. Less is the critical temperature of a gas, more easily it can be liquefied. Statement-2. Critical temperature is the temperature above which a gas cannot be liquiefied applying any amount of pressure.

In which of the following pairs of temperature scales, the size of a degree is idenital ? (i) mercury scale and ideal gas scale (ii) Celsius scale and mercury scale (iii) Celsius scale and ideal gas scale (iv) ideal gas scale and absolute scale

Which of following statements (s) is true I -Slope of isotherm at critical point is maximum. II-Larger is the value of T_(c) easler is the liquification of gas. III-Vander waals equation of state is applicable below critical temperature at all pressure.
