Does the density of an explosive gas effect the resulting damage an explsion may cause?
Yes. The force of the explosion is the same, but the force is more concentrated if it passes through a denser gas. In classical physics, there is no such thing as a “gas”. Particles free to move in three dimensional space are classified as liquids. Gasses are therefore liquids with very low density. In WWII, allied bombers were attempting to damage Germany’s hydroelectric capacity by destroying reservoir dams. They found detonating the charge up against the dam wall was inefficient. If the bomb exploded just in front of the wall, the water would serve as an effective battering ram. Special bombs were then designed to roll over the surface of the water, sink 20 feet in front of the wall and detonate on a time trigger. This phenomenon is also why submarines are so vulnerable to explosive charges dropped around them. Sperm whales are the animal equivalent of submarines. They swim to great depths and seem capable of stunning large prey by discharging a massive acoustic shock wave they focu
