Heating chloroform with aqueous sodium hydroxide solution forms

The potential difference between $A$ and $B$ in the figure is ................. $V$.

Which compound has the highest covalent character?

Two cylinders $A$ and $B$ fitted with pistons contain equal number of moles of an ideal monoatomic gas at $400 ~K$. The piston of $A$ is free to move while that of $B$ is held fixed. Same amount of heat energy is given to the gas in each cylinder. If the rise in temperature of the gas in $A$ is $42 ~K$,the rise in temperature of the gas in $B$ is (in $~K$)
