In a gaseous mixture which of $N{O}_2,C{O}_2,\mathrm{an}\mathrm{d }{N}_{2}O$ gases have the same rate of diffusion:

1. $N{O}_2$ $,$ $C{O}_2$

2. $C{O}_2$ $,$ $N_{2}O$

3. $N{O}_2$ $,$ $N_{2}O$

4. All of the above.

If 400 ml gas at 500 torrs and 666.6 ml gas at 600 torrs is taken in a container of 3 liters, then the total pressure of the mixture is:

1.  200 torr

2.  400 torr

3.  600 torr

4.  50 torr

The temperature of 4.0 mole of a gas occupying 5 dm³ at 3.32 bar is -
(R = 0.083 bar dm³ K^–1 mol^–1).

1. 40 K 

2. 30 K 

3. 20 K

4. 50 K 

The volume occupied by 8.8 g of CO₂ at 31.1°C and 1 bar pressure is:

(R = 0.083 bar L K^–1 mol^–1)

1. 4.05 L 

2. 3.05 L 

3. 6.05 L 

4. 5.05 L 

As per Charles's law ,–273° C is the lowest possible temperature because:

The correct relation between density ($\mathrm{\rho }$) and pressure of gas (P) is-

1. $\mathrm{P}$ $\mathrm{\alpha }$ ${\mathrm{d}}^2$

2. $\mathrm{P}$ $\mathrm{\alpha }$ $\frac{1}{\mathrm{d}}$

3. $\mathrm{P}$ $\mathrm{\alpha }$ $\mathrm{d}$

4. None of the above

A vessel of 120 mL capacity contains a certain amount of gas at 35 °C and 1.2 bar pressure. The gas is transferred to another vessel of volume 180 mL at 35 °C. The pressure would be-

1. 0.6 bar

2. 1.2 bar

3. 0.8 bar

4. 0.4 bar

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

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

Consider the following graph:

The curve that represents CO₂ gas is - 

1. X

2. Y
