(D) Given the condition $VP^2 = 	ext{constant}$.From the ideal gas equation, $PV = nRT$, so $V = nRT/P$.Substituting $V$ into the given condition: $(nRT/P) \cdot P^2 = 	ext{constant} \implies TP = 	ext{constant}$.Thus, $P \propto 1/T$, which represents a rectangular hyperbola on a $P-T$ diagram.Since $VP^2 = 	ext{constant}$, we have $P^2 \propto 1/V$, which means $P \propto 1/\sqrt{V}$.If the volume $V$ becomes $4V$, then the new pressure $P'$ is $P' \propto 1/\sqrt{4V} = (1/2) \cdot (1/\sqrt{V}) = P/2$.Therefore, both statements $(A)$ and $(B)$ are correct.

During an experiment, an ideal gas is found to obey a condition $VP^2 = \text{constant}$. The gas is initially at a temperature $T$, pressure $P$, and volume $V$. The gas expands to volume $4V$. Which of the following statements is correct?
