A rubber balloon was filled with helium at 25˚C and placed in a beaker of
liquid nitrogen at -196˚C. The volume of the cold helium was 15 cm3 Assuming ideal gas behavior and isobaric conditions, what was the volume
of the helium at 25˚C?

  1. Isobaric means constant pressure.
    V1/T1) = (V2/T2)
    Remember T must be in kelvi.
