Well, when I made a vortex using air, I used gases that are lighter.
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air.One way to weigh something that's lighter than air is to weigh it in a vacuum.
Because the gases filling the balloon are lighter than the surrounding air.
Anything less dense than air (hydrogen, helium, hot air).
The molecular weight of the gas or vapor plays a key role in determining whether it is lighter or heavier than air. Gases or vapors with lower molecular weights are typically lighter than air and will rise, while those with higher molecular weights are heavier and tend to sink. Temperature and pressure can also impact the behavior of gases and vapors relative to air.

No. The molar mass of dry air is 28.97 g/mol. Noble gases are monatomic, so their atomic mass represent their molar mass. From this we can tell that helium and neon are less dense (lighter) than air, while argon (atomic mass 39.9) onwards are denser than air.
Appended is a list of gases with their specific gravities. The specific gravity of a gas is a comparison of its density with that of air at the same temperature and pressure. Gases with a Specific Gravity (SG) less than1 are lighter than air.
Yes, farts are lighter than air because they are primarily composed of gases like methane and carbon dioxide, which are less dense than the surrounding air. This causes them to rise and disperse in the atmosphere.
Natural gas is lighter than air and rises.
CO is lighter than airAt 25 degrees Celsius and 1 atm of pressure, carbon monoxide's density is 1.145kg/m3, and the density of air is 1.1839kg/m3. So carbon monoxide is slightly lighter than air.
