you will have to add carbonate of soder and vineger its the easiest way!
A balloon filled with -2 degrees Celsius air will move to a room to a temperature of 8 degrees Celsius because of the collision of the air particles.
The speed of the particles inside the air-filled balloon increases as the temperature increases. This is because higher temperatures provide more thermal energy to the particles, causing them to move faster.
As it gets colder the air molecules move closer together and the balloon deflates.
It is filled with heated air. Since air is mostly nitrogen, a hot air balloon is mostly filled with nitrogen.
Helium is less dense than air, so a balloon filled with helium is lighter than the same volume of air. This buoyancy force allows the helium-filled balloon to rise. On the other hand, a balloon filled with air has the same density as the surrounding air, so there is no buoyant force to make it rise.
As you pull down the balloon at the bottom of the model, the air pressure inside the balloon increases, causing the air to be pushed out through the straw. This creates a propelling force that makes the balloon move in the opposite direction.
As temperature increases, the air molecules inside the balloon also heat up, causing them to move faster and exert more pressure on the walls of the balloon. This can cause the balloon to expand. Conversely, a decrease in temperature will cause the air molecules to slow down, resulting in a decrease in pressure and the balloon to shrink.
air
Putting an air-filled balloon in a refrigerator will cause it to shrink.
No it decreases
A balloon gets bigger when it is filled with air or gas because the molecules of air or gas inside the balloon move around and take up more space, causing the balloon to expand. The pressure from the air or gas inside the balloon pushes against the walls of the balloon, causing it to stretch and increase in size.
A water balloon is filled with water, and other balloons are filled with air or helium.
