Chemical, Physical and Thermal Properties of Helium - He
Chemical, physical and thermal properties of Helium - He :
(values at 25oC (77oF, 298 K) and atmospheric pressure)
Helium Black is designed with premium materials for all golfers looking for a lightweight shaft structure with extreme stability. Helium weighs 0.0001785 gram per cubic centimeter or 0.1785 kilogram per cubic meter, i.e. Density of helium is equal to 0.1785 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure. In Imperial or US customary measurement system, the density is equal to 0.01114 pound per cubic foot lb/ft³, or 0.00010318 ounce per cubic inch. Helium exists in Earth’s atmosphere only because it is constantly resupplied from three sources: decay of radioactive elements on Earth; primordial helium released from the planet’s crust by volcanic activity; and cosmic rays, about 9% of which are high energy helium nuclei. The Helium, formerly known as the Helium 3 or Helium LTA is the hallmark rod for Kistler Rods. For almost 20 years there’s been a Helium on the market. Used by Kistler pros to win big tournaments. It’s stood the test of time, and continues to be a fisherman’s favorite.
