During which process is all the heat absorbed by the system completely converted into work?

Enthalpy change for freezing of $1 \ g$ of water at $1 \ bar$ and $0^{\circ} C$ is $334 \ J$. Calculate the internal energy change in $J$ when $1 \ g$ of water is converted into ice?

If a system neither gains nor loses heat during its transformation from one state to another,such a process is called ......

Calculate the work done in the oxidation of one mole $HCl_{(g)}$ at $27^{\circ} C$,according to the reaction: $4 HCl_{(g)} + O_{2_{(g)}} \rightarrow 2 Cl_{2_{(g)}} + 2 H_{2}O_{(g)}$ $(R = 8.314 \ J \ K^{-1} \ mol^{-1})$ (in $J$)

On what factors does the enthalpy of dilution of a solution depend?

Fill in the blanks:
$(i)$ The process of attaining thermal equilibrium between any two heat-conducting bodies is called the $\dots\dots$ law of thermodynamics.
$(ii)$ The law of thermodynamics is actually the law of $\dots\dots$.
$(iii)$ $A$ thermometer measures temperature according to the $\dots\dots$ law of thermodynamics.
