Is helium an ideal gas
WebMar 26, 2016 · As it soars into the sky, you stop to wonder, as any physicist might, just how much internal energy there is in the helium gas that the blimp holds. The blimp holds 5,400 cubic meters of helium at a temperature of 283 kelvin. The pressure of the helium is slightly greater than atmospheric pressure, WebJan 6, 2024 · Helium, in particular, acts like an ideal gas because each atom is so tiny. Other gases behave much like ideal gases when they are at low pressures and temperatures. Low pressure means few interactions between gas molecules occur.
