for \mathrm{A B}
\mathrm{ P \propto \frac{1}{V} \Rightarrow P_2=P_1\left(\frac{v_1}{v_2}\right)=4 \times 10^7\left(\frac{1}{4}\right)=10^7 P_a }

For \mathrm{B C}

\mathrm{P V^r=} n constant
\mathrm{ \begin{aligned} p_3 & =p_1\left(\frac{v_1}{v_2}\right)^r=10^7\left(\frac{1}{2}\right)^{1.5} \\\\ & =3.53 \times 10^6 \mathrm{~Pa} . \end{aligned} }
