The diameter of a balloon filled by 8 moles He gas is 10 cm. If 7 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:
A
Solution:
At constant P,T, V ∝ n; only 1 mole remains, so V2 = V1/8. Diameter scales as V1/3: d2 = 10 × (1/8)1/3 = 10/2 = 5 cm. Matches (a).
