A rubber bladder with helium inside.
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
Helium balloons are typically made of a thin, flexible material such as latex or Mylar. The helium gas inside the balloon makes it float due to its low density compared to air. A small valve is usually attached to the balloon to allow for inflation and tying off the balloon.
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.
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
No. Helium is lighter than air
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
A balloon filled with helium flies because helium weighs less than air.
Helium!
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
helium balloon left in sun will expand. sun makes balloon hotter and density will rise balloon
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
helium is a light mass of weight in which will float unlike a hevy object that will fall to the ground

a helium balloon is forced upward by buoyancy. a object is forced upward by a force equal to the weight of the fluid it displaces. this also applies to gases. the gas helium is lighter than average atmospheric air, that is that equal volumes of atmospheric air and helium do not weigh the same. This means that the volume displaced by the balloon is heavier than the balloon itself. since the air weighs more it applies more force upwards on the balloon than the balloon applies downwards on the air, therefore it rises. However, a helium balloon will not go down unless a force such as large air resistance (heavy wind etc.) is applied to it. hope this helps.
depends how big the helium balloon is and how many
It was made out of the light gas gas Helium.
