At equilibrium,all systems are closed systems. $A$ saturated solution of glucose in an open vessel is which type of system?

Out of molar entropy $(I)$,specific volume $(II)$,heat capacity $(III)$ and volume $(IV)$,which are extensive properties?

An ideal gas expands from $1 \times 10^{-3} \ m^{3}$ to $1 \times 10^{-2} \ m^{3}$ at $300 \ K$ against a constant external pressure of $1 \times 10^{5} \ Nm^{-2}$. The work done is:

Which of the following is an isolated system?

Calculate the work done when $2$ moles of an ideal gas expand from a volume of $5 \ dm^3$ to $7 \times 10^{-3} \ m^3$ against a constant external pressure of $2.02 \times 10^5 \ Nm^{-2}$. (in $kJ$)

When $50 \ g$ of iron is dissolved in $HCl$ at $25 \ ^\circ C$ in a closed vessel,the work done is calculated to be ..... . The atmospheric pressure is $1 \ atm$. (in $J$)
