Interpretation: The relative densities of helium and air need to be explained.

Concept Introduction: The density of a substance is defined as mass per unit volume. If there are two gases, the one with lower density can float on the other.

Expert Solution & Answer

Answer to Problem 101A

The density of helium is less than air.

Explanation of Solution

According to the question, if a balloon filled with helium gas is released into the air, it will rise upward. Air contains oxygen and nitrogen gas molecules. The density of oxygen and nitrogen is more than helium. It shows that the density of helium is less than the density of air. Thus, a helium balloon floats in the air or rises upward in the air.

Conclusion

Thus, the density of helium is less than air.
