Liquefaction of Gases

The cascade method is used to liquify

The Andrew's experiment is the test for the validity of 

Which gas among the following is the easiest to liquify?

The critical temperature of ${\mathrm{O}}_2$ is less than ${\mathrm{H}}_2\mathrm{O}$ because the ${\mathrm{H}}_2\mathrm{O}$ molecules have:

The expression of $\mathrm{a}$in terms of ${\mathrm{P}}_{\mathrm{c}}$ and ${\mathrm{T}}_{\mathrm{c}}$ is:

From Andrew's Isotherm experiment can be calculated.

For which compound Andrew Thomson performed his experiment.

The critical volume of a gas when expressed in terms of Van der Waals constants $\mathrm{a}$ and $\mathrm{b}$ takes the form:

The van der Waals constant 'a' for different gases are given below:

The gas that can be most easily liquefied is

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

Maximum deviation from ideal gas is expected from:

If helium is allowed to expand in vacuum, it liberates heat because.

What is the correct increasing order of liquefiability of the gases shown as in the graph below?

The most favourable conditions to liquefy a gas are:-

The gas with the highest critical temperature is

For a real gas, the $\mathrm{P}-\mathrm{V}$ curve was experimentally plotted, and it had the following appearance. With respect to liquefaction. Choose the correct statement.

If for the gases, the critical temperature mentioned below i.e.:

${\mathrm{T}}_{{\mathrm{C}}_1}>{\mathrm{T}}_{{\mathrm{C}}_2}>{\mathrm{T}}_{{\mathrm{C}}_3}>{\mathrm{T}}_{{\mathrm{C}}_4}$

Which of the following can be predicted?

The gas which can be liquefied most easily is

An ideal gas can't be liquefied because :

Select the correct order followed by boyle's temperature $\left({\mathrm{T}}_{\mathrm{b}}\right)$, critical temperature $\left({\mathrm{T}}_{\mathrm{c}}\right),$ and inversion temperature $\left({\mathrm{T}}_{\mathrm{i}}\mathrm{ }\right)$.
