A certain mass of a gas occupies a volume of \(2 \mathrm{~L}\) at STP. To what temperature the gas must be heated to double its volume, keeping the pressure constant?
- A \(100 \mathrm{~K}\)
- B \(273 \mathrm{~K}\)
- C \(273^{\circ} \mathrm{C}\)
- D \(546^{\circ} \mathrm{C}\)
Answer & Solution
Correct Answer
(C) \(273^{\circ} \mathrm{C}\)
Step-by-step Solution
Detailed explanation
\(\frac{V_1}{T_1}=\frac{V_2}{T_2}(\) Charle's law \()\) \(\begin{aligned} \frac{2}{273} & =\frac{4}{T_2} \\ T_2 & =\frac{273 \times 4}{2}=546 \mathrm{~K} \text { or } 273^{\circ} \mathrm{C}\end{aligned}\)
