Two vessels separately contain two ideal gases $$\mathrm{A}$$ and $$\mathrm{B}$$ at the same temperature, the pressure of $$\mathrm{A}$$ being twice that of $$\mathrm{B}$$. Under such conditions, the density of $$\mathrm{A}$$ is found to be $$1.5$$ times the density of $$\mathrm{B}$$. The ratio of molecular weight of $$\mathrm{A}$$ and $$\mathrm{B}$$ is:

 1 $$\frac{2}{3}$$ 2 $$\frac{3}{4}$$ 3 $$2$$ 4 $$\frac{1}{2}$$

Volume, pressure, and temperature of an ideal gas are $$V$$, $$P$$, and $$T$$ respectively. If the mass of its molecule is $$m$$, then its density is: [$$k$$=Boltzmann's constant]

 1 $$mkT$$ 2 $$P \over kT$$ 3 $$P \over kTV$$ 4 $$Pm \over kT$$

Two thermally insulated vessels $$1$$ and $$2$$ are filled with air at temperatures $$\mathrm{T_1},$$ $$\mathrm{T_2},$$ volume $$\mathrm{V_1},$$ $$\mathrm{V_2}$$ and pressure $$\mathrm{P_1},$$ $$\mathrm{P_2}$$ respectively. If the valve joining the two vessels is opened, the temperature inside the vessel at equilibrium will be:
1. $$T_1+T_2$$

2. $$\frac{T_1+T_2}{2}$$

3. $$\frac{T_1T_2(P_1V_1+P_2V_2)}{P_1V_1T_2+P_2V_2T_1}$$

4. $$\frac{T_1T_2(P_1V_1+P_2V_2)}{P_1V_1T_1+P_2V_2T_2}$$

At $$10^{\circ}\mathrm{C}$$ the value of the density of a fixed mass of an ideal gas divided by its pressure is $$x$$. At $$110^{\circ}\mathrm{C}$$ this ratio is:
1. $$x$$
2. $$\frac{383}{283}x$$
3. $$\frac{10}{110}x$$
4. $$\frac{283}{383}x$$

An experiment is carried out on a fixed amount of gas at different temperatures and at high pressure such that it deviates from the ideal gas behaviour. The variation of $\frac{\mathrm{PV}}{\mathrm{RT}}$ with P is shown in the diagram. The correct variation will correspond to: (Assuming that the gas in consideration is nitrogen)
