A balloon filled with hydrogen can explode.
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)
The balloon filled with CO2 would go down most quickly at STP because it has the highest molar mass compared to CH4, N2, and O2. The rate at which a gas diffuses or rises is inversely proportional to the square root of its molar mass, so the heavier CO2 gas will descend faster.
A self-sealing rubber balloon filled with gas can be compressed when squeezed. The gas molecules inside the balloon move closer together, increasing the pressure of the gas. The balloon reverts to its original shape when the pressure is released.
balloons have carbion dioxide (vaccum) so in the world today vaccum is the best insulaters
When a balloon filled with helium or CO2 is placed in the refrigerator, the gas inside the balloon will contract and become denser due to the lower temperature. This will cause the balloon to deflate slightly or shrink in size. Once the balloon is removed from the refrigerator and returns to room temperature, the gas will expand again and the balloon will regain its original size.
Hydrogen.
The balloon is filled with a gas.
I captured hydrogen through a tube in a balloon. Then, with the balloon not all the way blown up, I put some oxygen in it. When I lit the balloon with a lighted punk it exploded with more heat and force than just a balloon with hydrogen. when the two gases were in the same balloon and not exploded they were added but not combined. When they exploded they became combined. Please, do not do this unless you have an experienced lab tech helping you.
A balloon filled with a gas will rise or sink depending on the density of the gas inside compared to the surrounding air. If the gas inside is less dense than the surrounding air, the balloon will rise. If the gas inside is more dense, the balloon will sink.
Calucus
A balloon! When a balloon is filled with air or gas and becomes overinflated, it can pop suddenly.
Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
The gas in the balloon is lighter than air. It has a specific gravity relative to air of less tha one.
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)
A balloon filled with light gas rises due to buoyancy generated by the difference in density between the gas inside the balloon and the surrounding air. However, as the balloon ascends, the air pressure decreases causing the gas inside the balloon to expand. Eventually, the gas will expand to the point where it equals the surrounding air density and the balloon will stop rising.
The number of atoms in a balloon would depend on the size of the balloon and the gas inside it. However, a typical sized balloon filled with helium might contain around 1x10^22 atoms.
A typical hot air balloon is filled with the same air we breath.
