So a helium balloon floats! Water has a higher density than air. The particles in a solid are tightly packed, so a lot of particles fit into a given space. This means solids have relatively high ...

The element is also employed in medical equipment such as lung ventilators, where a mix of oxygen and helium aids patients suffering from respiratory issues by reducing the density of the gas mixture.

This digital map visually represents Helium hotspotsaround the globe. Users can explore the coverage areas, identify network hotspots, and understand the density and distribution of HNT miners.

The Micromeritics helium gas displacement pycnometer allows the non-destructive measurement of volume and density of powder and solid materials. An inert gas (helium) is used as a displacement medium.
