A balloon contains 40.0 L of helium gas at 106.2 kPa. What is the volume of the helium when the balloon rises to an altitude where the pressure is only 35.0 kPa? (Assume that the temperature remains constant.)

✔ 最佳答案
Initial: V₁ = 40.0 L, P₁ = 106.2 kPaFinal: V₂ = ? L, P₂ = 35.0 kPa
For a fixed amount of gas at constant temperature: V₁/T₁ = V₂/T₂
Then, V₂ = V₁ × (T₂/T₁)
Final volume, V₂ = (40.0 L) × (35.0/106.2) = 13.2 L
