What else can I help you with?
As a helium filled balloon rises in the air it becomes?
Larger (the air pressure is dropping as it rises).
Why is a balloon more buoyant on a hot day?
the heat gives the molecules more energy to move around and rise.
Which has more volume a balloon filled with water or air?
The volum is similar, the mass is different.
Which has higher density balloon filled with water or helium?
I would say an air filled balloon if you fill it with just plain air. I am basing this on the principle of osmosis and diffusion. A substance such as a gas will travel from an area of increased concentration, such as a balloon filled with helium, to an area od decreased concentration, such as the room the balloon is in. If you fill the balloon with air identicle to that in the surrounding room it negates diffusion.
Why would a balloon filled with hydrogen on the surface pop 1km in the atmosphere?
As the balloon rises in the atmosphere, the air pressure decreases while the internal pressure of the hydrogen-filled balloon remains constant. This causes the pressure difference to increase, putting more stress on the balloon's material until it eventually pops due to the increased pressure difference.
Which has more buoyant force of atmospheric pressure an elephant or a small helium filled balloon?
Elephant. :)
As a helium filled balloon rises in the air it becomes?
Larger (the air pressure is dropping as it rises).
Is a hot-air balloon buoyant?
Yes, hot air balloons are less dense and therefore buoyant ============================================ Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.
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?
Which of a hydrogen filled balloon air filled balloon and a carbon dioxide filled balloon will deflate the fastest and which is the slowest and explain your answer?
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
Which balloon can deflate faster?
A balloon filled with helium will likely deflate faster than a balloon filled with air because helium molecules are smaller and can escape through the balloon material more easily.
Why is a balloon more buoyant on a hot day?
the heat gives the molecules more energy to move around and rise.
Why does a balloon filled with cold air falls to the ground?
Cold air is denser than warm air, therefore a balloon filled with cold air will weigh more than an identically sized balloon full of warm air. This extra weight causes the balloon to sink bellow warmer air. Cold air is denser than warm because as molecules become cooler they move more slowly causing them to be closer together.
Does the size of a balloon change the power of the pull?
yes it does
Why does a helium balloon rise in air while ordinary balloon filled with air does not?
A helium balloon rises into the air because the density of the helium is lesser than the density of the air, therefore, the balloon rises, trying to reach above the air. Helium is lighter than air, or to be more precise, less dense. Helium gas weighs less than our atmospheric air so it floats. Same goes for hydrogen and a few other pure gases
If a balloon is filled with more air its pressure increases then why it is called an intensive property?
ntensive property of a balloon
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.
