Is air more of less dense then water?
No everything is layered in density, water is much more dense than air. The whole planet is organized based on density with the core being the most dense and the exosphere being the least dense.
What can you say about the gas inside a balloon?
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
Is warm air less dense than cold air and moist air is more dense than dry air?
Warm air is less dense then cold air. But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
Are noble gases less dense than air?
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
Why does warm air weigh less than cold air?
Warm air has less pressure than cold air because it is less dense. As a gas is heated, its particles separate farther apart, making it less dense. Less dense gas creates less pressure. That is incorrect. Think of a pressurized tank of air, cold it has 120psi as you heat the pressurized tank up the pressure increases. It is because the molecules when cold are tightly packed and not bumping into each other as much as when warm and moving around bumping into one another.
Is heluim a gas a liquid or a solid?
helium is a gas less dense than air.
Is bromine gas denser or less dense than air?
yes
Is gas inside a hot air balloon less dense than a penny?
Yes. By definition, most gases are less dense than most solids. i can't think of a counter example. Plus, the gas inside a hot air balloon is superheated to make it even less dense, as heating things makes them less dense
What is less dense warm air or cold air?
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Is ammonia more dense or less dense than air?
Yes ammonia is less dense than air
Why hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
What can lift a balloon Other than helium?
Any gas which is less dense than air. Even hot air will suffice.
Is air more of less dense then water?
No everything is layered in density, water is much more dense than air. The whole planet is organized based on density with the core being the most dense and the exosphere being the least dense.
What is a colorless inert gas less dense than air is called?
i think its hellium helium
Why is air balloons filled with helium?
Because it is a safe gas that is less dense than air, thus balloons float in air
What makes balloons less dense air?
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
Why do helium-filled balloons raise in air?
Because helium is a less dense gas than a general air mixture
