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?

  1. A \(100 \mathrm{~K}\)
  2. B \(273 \mathrm{~K}\)
  3. C \(273^{\circ} \mathrm{C}\)
  4. D \(546^{\circ} \mathrm{C}\)
Verified Solution

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 \()\) \(\begin{aligned} \frac{2}{273} & =\frac{4}{T_2} \\ T_2 & =\frac{273 \times 4}{2}=546 \mathrm{~K} \text { or } 273^{\circ} \mathrm{C}\end{aligned}\)
