Calculate the work done in the following reaction at $300 \ K$ and at constant pressure. $(R = 8.314 \ J \ K^{-1} \ mol^{-1})$ $4 \ HCl_{(g)} + O_{2_{(g)}} \rightarrow 2 \ Cl_{2_{(g)}} + 2 \ H_2O_{(g)}$ (in $J$)

The relation between $\Delta H$ and $\Delta U$ is

In thermodynamics,a process is called reversible when

Observe the following properties: Volume,enthalpy,density,temperature,heat capacity,pressure,internal energy. The number of extensive properties in the above list is

When $5 \ mol$ of $He$ gas expand isothermally and reversibly at $300 \ K$ from $10 \ L$ to $20 \ L,$ the magnitude of the maximum work obtained is $....... \ J$. [nearest integer] (Given: $R = 8.3 \ J \ K^{-1} \ mol^{-1}$ and $\log 2 = 0.3010$)

For a thermodynamics system,which among the following is not a state function?
