Kelly's Exciting Hydrogen Balloon Experiment!
What evidence would support Kelly’s prediction about the hydrogen balloons?
A) All three balloons climb to the same height
B) Balloon A climbs higher than Balloon B and Balloon C
C) Balloon B climbs higher than Balloon A and Balloon C
D) Balloon C climbs higher than Balloon A and Balloon B
Answer: Balloon C climbs higher than Balloon A and Balloon B
Explanation: Kelly predicted that the balloon filled with the most hydrogen gas would climb higher than the others. To support this prediction, scientific evidence shows that in this scenario, Balloon C, which was filled to a volume of 120 cubic inches, climbs higher than both Balloon A and Balloon B. This demonstrates the relationship between hydrogen gas volume and the height the balloons can reach.
Kelly's hydrogen balloon experiment is not only educational but also exciting to witness. By filling Balloon C with the most hydrogen gas and observing it climb higher than the other two balloons, Kelly has successfully demonstrated a scientific principle in action.
The correlation between the volume of hydrogen gas in the balloons and their respective climbing heights provides concrete evidence to support Kelly’s prediction. As the volume of hydrogen gas increases, so does the buoyancy of the balloons, allowing them to reach greater heights in the atmosphere.
This experiment showcases the importance of scientific evidence in drawing conclusions. By carefully observing the behavior of the hydrogen-filled balloons, Kelly was able to confirm her hypothesis and deepen her understanding of the principles of aerodynamics.
