The diameter of a balloon filled by 27 moles He gas is 12 cm. If 26 moles He gas effuses out in the night, what should be the diameter of balloon in the next morning? Assume constant pressure and temperature for the gas.
Options:
Answer:
C
Solution:
At constant P,T, V ∝ n; 1 mole remains, so V₂ = V₁/27. Diameter scales as V1/3: d₂ = 12 × (1/27)1/3 = 12/3 = 4 cm. Matches (c).
