Out of $E, H, G, q$ and $w$,which are state functions?

$A$ given mass of gas expands from state $A$ to state $B$ by three paths $1, 2$ and $3$ as shown in the figure. If $w_1, w_2$ and $w_3$ are the work done by the gas along the three paths respectively,then:

For which of the following reactions is $\Delta H$ approximately equal to $\Delta E$?

For a reversible process at $T = 300 \, K$,the volume increases from $V_i = 1 \, L$ to $V_f = 10 \, L$. If the process is isothermal,find the value of $\Delta H$ in $kJ$.

Which among the following pairs of properties are intensive?

What is the value of $\Delta H - \Delta U$ for the following reaction? $2 C_{(s)} + 3 H_{2(g)} \rightarrow C_2H_{6(g)}$
