A balloon is filled at \(27^{\circ} \mathrm{C}\) and 1 atmospheric pressure by volume \(500 \mathrm{~m}^3\) helium gas. At \(-3^0 \mathrm{C}\) and 0.5 atmospheric pressure, the volume of helium gas will be
- A \(500 \mathrm{~m}^3\)
- B \(700 \mathrm{~m}^3\)
- C \(900 \mathrm{~m}^3\)
- D \(1000 \mathrm{~m}^3\)
Answer & Solution
Correct Answer
(C) \(900 \mathrm{~m}^3\)
Step-by-step Solution
Detailed explanation
\(T_1 = 27 + 273 = 300 \mathrm{~K}\) \(T_2 = -3 + 273 = 270 \mathrm{~K}\)
