(C) For an adiabatic compression,the relation is $PV^{\gamma} = \text{constant}$.Given: $V_{\text{new}} = \frac{1}{4} V$ and $\gamma = \frac{3}{2}$.Using the adiabatic process equation:$P_1 V_1^{\gamma} = P_2 V_2^{\gamma}$$P \cdot V^{\gamma} = P_{\text{new}} \cdot \left(\frac{V}{4}\right)^{\gamma}$$\frac{P_{\text{new}}}{P} = \left(\frac{V}{V/4}\right)^{\gamma} = (4)^{\gamma}$$\frac{P_{\text{new}}}{P} = (4)^{3/2} = (2^2)^{3/2} = 2^3 = 8$Therefore,$P_{\text{new}} = 8P$.
