38. The volume of an ideal gas changes as the gas undergoes an isobaric (constant pressure) process starting from temperature `

273{ }^{\circ} \mathrm{C}

` and ending at `

546^{\circ} \mathrm{C}

`. What is the ratio of the new volume of the gas to the old volume `

\left(\mathrm{V}_{\text {new }} / \mathrm{V}_{\text {old }}\right)

` ? (A) `

\frac{1}{2}

` (B) `

\frac{2}{3}

` (C) `

\frac{3}{2}

` (D) 2
