An ideal gas is allowed to expand from $1 \, L$ to $10 \, L$ against a constant external pressure of $1 \, bar$. The work done in $kJ$ is

Which of the following is not a state function of a thermodynamic system?

Identify the pair in which both are not extensive properties.

If $5 \ mol$ of an ideal gas expands from $10 \ L$ to a volume of $100 \ L$ at $300 \ K$ under isothermal and reversible conditions,then the work done,$w$,is $-x \ J$. The value of $x$ is $ . . . . . . $. (Given $R = 8.314 \ J \ K^{-1} \ mol^{-1}$)

The heat of combustion of benzene determined in a bomb calorimeter is $-870 \ kcal \ mol^{-1}$ at $25 \ ^oC$. The value of $\Delta E$ for the reaction is......$kcal$.
