Description : Do gases with high molar masses travel through small openings faster than gases with low molar masses?
Last Answer : answer:I wouldn’t think so, unless you include a propellant. Sorta like with the aerosol can. I don’t expect mass to matter much unless you’re driving the gas gravitically. All things being equal, I’d guess that you’re looking at the same rate of flow in both cases. But then, I’m no physicist.
Description : Can wind travel faster than the speed of sound? -Geography
Last Answer : Yes, wind can travel faster than the speed of sound. Wind is just the bulk movement of a mass of air through space and is in principle no different from a train speeding along or a comet zipping through space.The speed of sound just describes how fast a mechanical wave travels through a material.
