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.

What are the six gases than are less dense than air?
Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.
Are noble gases less dense than air?
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
Greenhouse gases are obviously lighter than air How then are they measured by weight How does one weigh something that is lighter than 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.
What gases lift a balloon into the air?
Anything less dense than air (hydrogen, helium, hot air).
Does propane weigh less than air?
Actually it is heavier than air. And it will sink much like co2 does in air
Why you weigh more in the air than in the water?
because there is less gravity in water
Why does a hot air balloon rise with hot air?
Hot air is less dense than cooler air. This makes it weigh less then the surrounding air so it rises.
Which gases weigh more than air Im aware that helium qualifies but also you are aware that you have few known sources of this gas IE What other gasses are a viable choice for diving?
- Helium is less dense than air. - For diving, as diluents for oxygen nitrogen and helium are used.
What is the difference between upward and downward delivery?
If you r talking about gases Downward delivery:-collecting gases which are denser than air. e.g. carbon dioxide, chlorine. upward delivery :-collecting gases which are less dense than air. e.g. hydrogen.
Why does cold gases and liquids sink?
Hot air is less dense than the surrounding air and therefore it rises. Cold air, on the other hand, is the opposite. It is more dense than surrounding air and sinks.
If you trap air in a balloon and put it into warm air will it float?
If the air in the balloon is cooler than the air around it, it will sink. Hot air balloons go up because they weigh less than the air around them.
Does air pressure affect water pressure?
Water Vapor affects pressure because moist air contains many heavy gases such as O2,N2 etc. But less water vapor. Since these gases are heavier than water vapor, it becomes more dense constituting more pressure. So Moist air contains less pressure than Dry Air.
