What else can I help you with?
When would less helium be needed to fill a balloon?
The lower the atmospheric pressure, the less helium is needed.
Will a balloon half filled with air other half helium float?
Yes, a balloon that is half-filled with air and the other half with helium will float because helium is lighter than air. The helium will cause the overall density of the balloon to be lower than the surrounding air, resulting in it floating.
Why a helium weather balloon expands as it rises in the air. assume that the temperature remain constant.?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.
How is the helium in the tank different from the helium in the balloon?
Helium balloons are usually mylar, a metal-coated plastic film while blow-up balloons are usually latex. Helium balloons are usually filled with helium of a decent purity, while blow-up balloons basically have the same gas mixture as the atmosphere around us. A little less oxygen and a little higher humidity if inflated by humans, exactly the same if inflated by a pump. Helium balloons will fly or float in the air, while blow-up balloons won't.
Why do helium balloons shrink and stop floating?
Helium filled balloons stop floating because the helium leaks out. The balloon latex is porous and the helium is a very small atom and leaks out causing the balloon to lower and eventually stop floating.
How much can a helium balloon lift?
depends how big the helium balloon is and how many
What happens when a helium-filled balloon is released and rises into the atmosphere?
As the helium-filled balloon rises into the atmosphere, the surrounding air pressure decreases while the pressure inside the balloon remains the same. This causes the helium inside the balloon to expand, making the balloon increase in size. Eventually, the balloon will reach a point where the difference in pressure between the inside and outside of the balloon will be equal, and it will float at that altitude.
When a helium balloon rises in the air it expands. If the volume of the balloon doubles what happens to the density of the helium inside it?
If the volume of the helium balloon doubles as it rises, the density of the helium inside it decreases. This is because the same amount of helium gas is now spread out over a larger volume, leading to a lower density.
Why does a helium balloon go up?
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
What was the helium balloon balloon made of?
It was made out of the light gas gas Helium.
What is the answer for it already has helium but what is it?
The object that already has helium is most likely a helium-filled balloon. Helium is used to inflate balloons as it is lighter than air, causing the balloon to float.
What makes a child's balloon rise?
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
