Chapter 14, Problem 44R

To determine

The changes that occur inside a helium balloon as it rises from the sea level.

Answer to Problem 44R

The volume of the helium inside the helium balloon increases as it rises from the sea level.

Explanation of Solution

Introduction:

The atmospheric pressure of the air decrease with increasing elevation of the object. The volume of the gasses increases with height due to decrease in the pressure.

The helium is lighter than the surrounding air, so it rises rapidly in upward direction. As the helium balloon rises up the pressure of the atmospheric air on the balloon decrease. So, the volume of the helium inside the balloon starts increasing.

Conclusion:

Thus, the volume of the helium inside the helium balloon increases as it rises from the sea level.
