Concentration of the ${\text{Ag}}^{+}$ ions in a saturated solution of ${\text{Ag}}_2{\text{C}}_2{\text{O}}_4$ is $2.2\times 10^{-4}{\text{mol L}}^{-1}$. Solubility product of ${\text{Ag}}_2{\text{C}}_2{\text{O}}_4$ is:

Ionic mobility of which of the following alkali metal ions is lowest when aqueous solution of their salts are put under an electric field?

A gas expands in a well insulated container against a constant external pressure of $2.5\text{atm}$ from an initial volume of $2.50\text{L}$ to a final volume of $4.50\text{L}$. The change in internal energy $\Delta U$ of the gas in joules will be:
