Pressure on an object as it rises up into the atmosphere

  1. Jan 23, 2009 #1
    how would you find the pressure on an object as it rises up into the atmosphere

    ex.
    A child's helium-filled balloon escapes at sea level and 20.0°C. It reaches an altitude of 3330 m, where the temperature is 5.0°C and the pressure only 0.65 atm. What is the ratio of its volume at this altitude to its volume at sea level?
