Which gas would readily flow on the ground if it was released 1 chlorine 2 ethyne 3 Helium 4 hydrogen 5 nitrogen
1. Chlorine gas (Cl2) would not readily flow on the ground if released. It is denser than air and tends to stay closer to the ground, but it is not a gas that readily flows like a liquid.
2. Ethyne gas, also known as acetylene (C2H2), would readily flow on the ground if released. Acetylene is lighter than air and would disperse quickly, flowing along the ground if there is no obstruction.
3. Helium gas (He) would readily flow on the ground if released. Helium is much lighter than air, and due to its buoyancy, it tends to rise upwards. However, if it is released at ground level, it would spread along the ground.
4. Hydrogen gas (H2) would readily flow on the ground if released. Like helium, hydrogen is lighter than air and tends to rise. However, if it is released at ground level, it would quickly flow horizontally along the ground.
5. Nitrogen gas (N2) would not readily flow on the ground if released. Nitrogen is similar in density to air and would disperse in the surrounding atmosphere rather than flowing along the ground.
