An ideal gas initially at \(0^{\circ} \mathrm{C}\) temperature is compressed suddenly to one fourth of its volume. If the ratio of specific heat at constant pressure to that at constant volume is \(3 / 2\), the change in temperature due to the thermodynamics process is ________ K.

Solution

$\begin{aligned} & \gamma=\frac{3}{2} \\ & \mathrm{Tv}^{\gamma-1}=\mathrm{C} \\ & 273 \mathrm{~V}_0^{0.5}=\mathrm{T}\left(\frac{\mathrm{V}_0}{4}\right)^{0.5} \\ & \mathrm{~T}=273 \times 2=546 \\ & \Delta \mathrm{~T}=273\end{aligned}$
