Prof. Anil Thomas and Prof. Santosh Yadav Solutions for Chapter: States of Matter (Gases and Liquids), Exercise 3: Competitive Thinking

An ideal gas obeying the kinetic theory of gases,                 

$\mathrm{A}\text{,} \mathrm{B}\text{,} \mathrm{C}$ and $\mathrm{D}$ are four different gases with the critical temperatures $304.1$, $154.3$, $405.5$ and $126.0$ $\mathrm{K}$, respectively. While cooling, the gas which gets liquefied first is                

The gas that liquefies first, when cooled from $500 \mathrm{K}$ to its critical temperature given in-parenthesis is _____________                        
                                                                                                               

Which of the following is NOT true in case of an ideal gas?
