Question

A balloon contains 500 m³ of helium at 27⁰C and 1 atmosphere pressure. The volume of the helium at –3⁰C temperature and 0.5 atmosphere pressure will be-

• A. 500 m³
• B. 700 m³
• C. 900 m³
• D. 1000 m³

Answer 1

Answer: (C)

900 m³

Answer 2

$\frac{P_{1}V_{1}}{T_{1}}$=$\frac{P_{2}V_{2}}{T_{2}}$Ž $\frac{1 \times 500}{300}$=$\frac{0.5 \times V_{2}}{270}$Ž V₂ = 900m³
