    What is the volume ratio of a helium balloon at different altitudes?

    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? PV/T=PV/T i got .94

    Undergrad Pressure on an object as it rises up into the atmosphere

    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...
