Out of helium with density 0.18 and hydrogen 0.09 which one of those would flow more readily along the ground if accidentally released
1 answer
If accidentally released, helium would flow more readily along the ground compared to hydrogen. This is because helium is lighter than hydrogen and has a lower density (0.18 g/cm³) compared to hydrogen (0.09 g/cm³). The lower the density, the more easily a gas can disperse and move through the air or along the ground. Therefore, helium would flow more readily.
