Gases possess characteristic critical temperature which depends upon the magnitude of intermolecular forces between the gas particles. Critical temperatures of ammonia and carbon dioxide are 405.5 K and 304.10 K respectively. The gas liquify first when cooling start from 500 K to their critical temperature, is-

1. Ammonia

2. Carbon dioxide

3. Both liquify at same time

4. Cannot predict

A plot of pressure versus $\frac{1}{\mathrm{V}}$ for a gas at constant temperature is given below:

The relation between ${\mathrm{T}}_1, {\mathrm{T}}_2, \mathrm{and} {\mathrm{T}}_3$ is- 

 $1. {\mathrm{T}}_1>{\mathrm{T}}_2>{\mathrm{T}}_3$
$2. {\mathrm{T}}_1<{\mathrm{T}}_2<{\mathrm{T}}_3$
$3. {\mathrm{T}}_1>{\mathrm{T}}_2<{\mathrm{T}}_3$
$4. \mathrm{None} \mathrm{of} \mathrm{the} \mathrm{above}$

The variation of pressure with the volume of the gas at different temperatures can be
graphically represented as per the following graph:

If the temperature increases from 200K to 400K (at constant pressure), the volume of a
gas would-  

1. Increase

2. Decrease

3. Remain constant

4. 1st decreases then increases

Consider the following graph:

The curve that represents CO₂ gas is - 

1. X

2. Y

3. Both X and Y 

4. Cannot predict from the graph

Pressure versus volume graph for a real gas and an ideal gas is shown below: 

The correct statement among the following is -

2. Real gases show a very small deviation from ideal behaviour at low pressure.

3. Real gases do not behave ideally under any conditions at low pressure.

4. None of the above statements is correct
