Liquefaction of Gases

According to the Thomas Andrews, what is the critical temperature (${\mathrm{T}}_{\mathrm{c}}$) of carbon dioxide?

The critical volume of a gas is $0.036 \mathrm{l}.{\mathrm{mol}}^{-1}$ . What will be the radius of the molecule in $\mathrm{cm}$?

The radius of a molecule is $1.5\times {10}^{-8} \mathrm{cm}$. Calculate the critical volume of the gas.

The critical volume of a gas is $0.072 \mathrm{l}.{\mathrm{mol}}^{-1}$ . What will be the radius of the molecule in $\mathrm{cm}$?

What is critical volume? Give its formula.

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:

Define critical temperature of the gas. Give its expression.
