A $1 \mathrm{L}$ flask contains nitrogen at a pressure of $100 \mathrm{kPa}$ and another $3 \mathrm{L}$ flask contains oxygen at pressure $\mathrm{P}$. If the two flasks are connected, the resultant pressure becomes $265 \mathrm{kPa}$. What is the value of $\mathrm{P}$?

In the above $\mathrm{P}-\mathrm{V}$ curve, at a constant temperature, what can be ${\mathrm{T}}_1$ and ${\mathrm{T}}_2$ (in Kelvin) respectively?

The apparatus shown above consists of three bulbs connected by stop cocks. What is the pressure inside the system, when stop cocks are open? (Assume that temperature remains constant) 

Two balloons, $\mathrm{A}$ and $\mathrm{B}$ are filled with a gas at $300 \mathrm{K}$. Maximum capacities of balloons, A and B are $1000$ and $2000 \mathrm{mL}$, respectively. When the balloon system is heated, which one will burst first?
