Which of the following is not a state function?
$(I) \, q + W \, (II) \, q \, (III) \, W \, (IV) \, H - TS$

Which of the following is an intensive property?

$A$ gas absorbs a certain amount of heat and expands by $200 \ cm^3$ against a constant external pressure of $2 \times 10^5 \ Nm^{-2}$. What is the work done by the system (in $J$)?

An ideal gas is allowed to expand from $2 \ dm^3$ to $6 \times 10^{-3} \ m^3$ against a constant external pressure of $1 \ bar$. The work done in $kJ$ is (in $kJ$)

For the reaction,$2Cl_{(g)} \to Cl_{2_{(g)}}$,what are the signs of $\Delta H$ and $\Delta S$?

The volume of $100 \ L$ of gas increases to $120 \ L$ at a constant temperature and an external pressure of $10 \ bar$. Calculate the work done by the system. [Given: $1 \ L \ bar = 24.21 \ cal$] (in $cal$)
