The gas is hot air.
A balloon has a certain weight due to the material it's made of. When you blow air into the balloon, the weight of the air inside balances out the weight of the balloon material, making the total weight of the balloon and air the same as the original balloon.
if you think about it, air molecules increase more and more. And the balloon has it flexibility. But the balloon can only stretch out a far distance. Henceforth, too much air molecules from you will make the balloon pop
When you fill a balloon with air, the air molecules displace the surrounding space inside the balloon, causing the balloon to expand and stretch. The pressure of the air inside the balloon exceeds the pressure outside, creating tension in the balloon material, which keeps it inflated.
Blowing air into a balloon increases the pressure and stretches the balloon material. If you blow too much air, the pressure inside the balloon exceeds the elastic limit of the material, causing it to burst.
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
with material
The hot air balloon has a basket in the middle, which holds passengers and the pilot. The basket is attached to the envelope of the balloon, where hot air is used to generate lift and make the balloon float.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
A balloon is made of stretchable material that can expand as air is blown in. The pressure inside the balloon increases as it expands, but the material can stretch to accommodate the increased pressure without exploding.
yes, but when using Helium you must have the balloon completely sealed and used a mylar material for the balloon as Helium 'leaks-out' of ordinary materials.
When the balloon is inflated, it is filled with air, which has less mass than the solid material of the deflated balloon. So overall, the balloon has less mass when inflated because the mass of the air inside it is lighter than the solid material of the balloon.
The weight of a balloon without air is approximately the weight of the material the balloon is made from. This weight can vary depending on the size and material of the balloon, but it is generally very light, often just a few grams.
