Question

Two bulbs of volume 100 c m 3 and 200 c m 3 are joined by a narrow tube and filled with air at one pressure at 1 2 ∘ C. The small bulb is placed in melting ice and the large bulb in boiling water. Find the fraction of the air in the large bulb (two decimals).

TestHub · Accepted Answer

n ∝ ( V ) / ( T ) at the same pressure. Large: ( 200 ) / ( 373 ) = 0.536 . Small: ( 100 ) / ( 273 ) = 0.366 . Fraction = ( 0.536 ) / ( 0.902 ) = 0.59 .
