Helium which is a lighter-than-air gas, allowing the balloon to float upwards.
Helium is stored under pressure, so a lot is packed into a small space. The gas in the balloon is at only slightly more than normal air pressure. The helium spreads out as it fills the balloons.
No, it is a gas-solid mixture when view as a whole. It has a solid component (the balloon itself), and a gas component (the helium)
Helium typically fills a balloon faster than air because it is less dense than air and flows easily into the balloon. Helium is also less likely to escape from the balloon due to its smaller molecular size compared to the molecules in air.
depends how big the helium balloon is and how many
It was made out of the light gas gas Helium.
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.
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
As it rises, outside air pressure decreases, and the hot air inside expands and fills the balloon. Same thing is true of large helium balloons.
The balloon with helium.
A helium balloon is made by filling a latex or mylar balloon with helium gas, which is lighter than air, causing the balloon to float. The helium gas is sealed inside the balloon, allowing it to stay afloat for a period of time before slowly deflating.
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
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.
