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 $$\frac{1}{2}$$

An isolated system-

 1 is a specified region where transfer of energy and mass takes place 2 is a region of constant mass and only energy is allowed through the closed boundaries 3 is one in which mass within the system is not necessarily constant. 4 cannot transfer neither energy nor mass to or from the surroundings.

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