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

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 vapour pressure of different liquids with temperature is shown below:

Boiling points of liquids A and B are, respectively

1. 311 K and 374 K

2. 298 K and 353 K

3. 307 K and 337 K

4. Cannot be determined from the graph given above

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 -

1. Real gases show a large deviation from ideal behaviour at low pressure.

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

The plots of different values of pressure versus temperature are shown in the given figure. The correct order of volume for the following plot is-

1. V₄ < V₃ < V₂ < V₁

2. V₄ > V₃ < V₂ > V₁

3. V₄ > V₃ > V₂ > V₁

4. V₄ > V₃ > V₂ < V₁
