Helium can be used instead of hydrogen in balloons for meteorological research.Reason:- Hydrogen is explosive I presence of air and may explode causing serious accidents.- Helium is less dense than hydrogen.7. Helium is used in thermometers for measurements f very low temperatures.8. Liquid helium is used to keep certain metal alloys at temperatures low enough for them to become superconductors.
