Is a balloon more dense or less dense than the surrounding air?

Because that's what density does.
Whenever an object is immersed in a medium with higher density than the object, the object will try to rise to apoint where its buoyancy(lifting force) equals the pull of gravity.

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.
Air is warmer and less dense than surrounding air at the equator because the equator receives more?
Air pressure
Why does a helium filled balloon rise in relation to its density?
I'm not sure I understand the question but here goes: Helium is lighter [less dense] than air, so a helium filled balloon rises because it floats up on the more dense air.
How call you tell if a substance is more or less dense then water?
if it sinks its more dense if it floats its less dense
Does more dense or less dense objects settle faster?
More dense.
Why would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Is a cannon ball more or less dense than a water balloon the same size?
less dense
How does a hot air balloon work?
Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.
How does air help to make a hot air balloon work?
Air has a certain density. A hot air balloon heats air inside the balloon which causes it to become less dense. This is because the hotter something is, the more space it takes up. Less dense things float on top of more dense things (think of oil on water). You get enough less dense hot air, and the balloon will float up on top of the cold, dense air.
Are helium balloons more dense than air baloons?
No. At the same pressure, a helium filled balloon will be less dense than an air-filled balloon.
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.
How does a balloon filled with nitrogen air fly up?
The composition of air is roughly 78% nitrogen and the remainder except a negligable amount of hydrogen is more dense than nitrogen. Therefore a balloon filled with nitrogen will be less dense then the surrounding air and thus will rise. The balloon will probaly not rise, as there is insufficient lift to overcome the weight of the balloon fabric. Are you sure you don't mean Helium, or Hydrogen?
THE HOT ROCK IN THE ASTHENOSPHERE RISE TO THE LITHOSPHERE BECAUSE IT IS LESS OR MORE DENSE THAN SURROUNDING MATERIALS?
the answer is less
How do hot air balloons use the principle of bouyancy?
Hot air balloons heat up contained air so that the density of it becomes significantly less than the outside air and thus the container (balloon) will rise of float in the surrounding air until the density difference is null. Buoyancy is just that, less dense substances floating or rising in more dense substances. The other approach is saying more dense substances sink in less dense substance.
If you were to turn on the burner on in the hot air balloon what effect would it have on the air in the balloon?
When the burner on a hot air balloon is turned on the air inside the balloon is heated making it less dense. This will cause the balloon to be more buoyant and climb.
Do convection currents form in the mantle when heated materials become more dense?
Yes, convection currents form in the mantle due to the heating and cooling of material, which causes density differences and drives the movement of material. When material in the mantle is heated, it becomes less dense and rises, while cooler, denser material sinks, creating a circulation pattern known as mantle convection.
How does density volume and mass makes the hot air balloon to work?
Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise ad the volume becomes more. Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise and the volume becomes more.
