Q3 / 58 · KVPY 2016 (SA) · Chemistry
In a closed vessel, an ideal gas at $1 \mathrm{~atm}$ is heated from $27^{\circ} \mathrm{C}$ to $327^{\circ} \mathrm{C}$. the final pressure of the gas wil approximately be
- A3 atm
- B$0.5 \mathrm{~atm}$
- Correct answerC2 atm
- D12 atm
Solution
$\mathrm{P} \propto \mathrm{T}(\mathrm{V}, \mathrm{n} \rightarrow$ const $)$
$\frac{\mathrm{P}_{1}}{\mathrm{P}_{2}}=\frac{\mathrm{T}_{1}}{\mathrm{~T}_{2}}$
$\frac{1}{\mathrm{P}_{2}}=\frac{300}{600}$
$\mathrm{P}_{2}=2 \mathrm{~atm}$
Hence, the correct answer is option: 'C'.
