Question

Weather balloons are filled with helium because:
  1. Less reactive 
  2. Condenses at very low temperature
  3. Heavier than hydrogen
  4. lighter than air


Solution

The correct option is D lighter than air
Hydrogen and helium are very light gases and can be used to fill weather balloons. However, hydrogen is very inflammable and hence is dangerous to use in balloons. So, helium is preferred for this purpose.
