In the Fig.-2, let $P_2=10\times10^5$Nm$^{-2}$, $P_1=4\times10^5$Nm$^{-2}$, $v_1=2.5$m$^3$kilomole$^{-1}$. Find

1. the temperature $T$,
2. the specific volume $v_2$,
3. the temperature at points $b$ and $d$,
4. the actual volume $V$ at point $a$ if the system consists of 4 kilomoles of hydrogen,
5. the mass of hydrogen.
