To Explain: The use of helium in balloons over hydrogen.
Answer to Problem 37R
Helium is used in balloons because it is stable has a low density.
Explanation of Solution
Introduction:
The density of both Hydrogen and Helium is less than that of air.
Helium is used in balloons instead of hydrogen because helium is a stable and a noble gas whereas hydrogen is the lightest gas but it is flammable and an explosive gas. The density of the helium gas is also low and it is a not flammable gas. So due to the properties difference between the hydrogen and the helium, helium is preferred in balloons.
