$A$ and $B$ are ideal gases. At $T(\mathrm{~K}), 2 \mathrm{~L}$ of ' $A^{\prime}$ 'with a pressure of 1 bar is mixed with 4 L of ' $B$ ' with a pressure $p_B$ bar in a 100 L flash. The pressure exerted by gaseous mixture is 0.1 bar. What is the value of $p_B$ in bar?

126. Consider the following

Statement I If thermal energy is stronger than intermolecular forces, the substance prefers to be in gaseous state.

Statement II At constant temperature, the density of an ideal gas is proportional to its pressure.

The correct answer is

At $27^{\circ} \mathrm{C}, 1 \mathrm{~L}$ of $\mathrm{H}_2$ with a pressure of 1 bar is mixed with 2 L of $\mathrm{O}_2$ with a pressure of 2 bar in a 10 L flask. What is the pressure exerted by gaseous mixture in bar? (Assume $\mathrm{H}_2$ and $\mathrm{O}_2$ as ideal gases)

Choose the incorrect statement from the following.
