    Two gases occupy two containers $A$ and $B$ the gas in $A$, of volume $0.10\,m ^3$, exerts a pressure of $1.40\,MPa$ and that in $B$ of volume $0.15 m ^3$ exerts a pressure $0.7\,MPa$. The two containers are united by a tube of negligible volume and the gases are allowed to intermingle. Then if the temperature remains constant, the final pressure in the container will be (in MPa)

    A container with rigid walls is covered with perfectly insulating material. The container is divided into two parts by a partition. One part contains a gas while the other is fully evacuated (vacuum). The partition is suddenly removed. The gas rushes to fill the entire volume and comes to equilibrium after a little time. If the gas is not ideal, then

    An engineer is given a fixed volume $V_m$ of metal with which to construct a spherical pressure vessel. Interestingly, assuming the vessel has thin walls and is always pressurized to near its bursting point, the amount of gas the vessel can contain, $n$ (measured in moles), does not depend on the radius $r$ of the vessel : instead it depends only on $V_m$ (measured in $m^3$) the temperature $T$ (mensured in $K$). the ideal gas constant $R$ (measured in $J/(K\ mol$ )), and the tensile strength of the metal $\sigma $ (measured in $N/m^2$ ) . Which of the following gives $n$ in terms of these parameters?
