Why does the air change the shape and size of the balloon?
Because the air is coming inside the balloon.
Why do balloons change the shape when you blow air into it?
When you blow air into a balloon, the air molecules push against the rubber walls of the balloon, causing them to stretch and expand. The pressure of the air inside the balloon is higher than the pressure outside, which causes the balloon to inflate and change its shape.
Is filling a balloon with hot air a chemical or physical change?
Filling a balloon with hot air is a physical change because the hot air is simply expanding and occupying more space within the balloon, without any change in its chemical composition.
Is a hot air balloon rising a chemical change?
No, a hot air balloon rising is a physical change, not a chemical change. The balloon rises because the air inside it is heated, causing it to expand and become less dense than the surrounding air, which causes it to float upwards.
Why does an air balloon float?
If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
Is heating the air in a balloon a chemical change or a physical change?
Heating the air in a balloon is a physical change because it does not involve any chemical reactions. The heat causes the air molecules to move faster, increasing their kinetic energy and causing the balloon to expand.
Does heat make things fly?
Heat alone does not make things fly. However, heating air can affect the movement of objects in the air. For example, hot air balloons rise because the air inside the balloon is heated, making it less dense than the surrounding air, causing the balloon to float upwards.
Is blowing up a balloon an irreversible change?
Blowing up a balloon is a reversible change because the process can be reversed by letting the air out of the balloon. The balloon returns to its original state before it was blown up.
Why does the shape and size of a balloon change when filled with air or water?
The shape and size of a balloon change when filled with air or water because the molecules of the substance fill the balloon and exert pressure on its walls. This pressure causes the balloon to expand and take on the shape of its contents. The volume of the balloon increases as more air or water is added, changing its size accordingly.
Why does a balloon burst when near some hot air?
The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
Is blowing in a balloon is a physical change?
Yes, It is a physical change because it's only losing air. when you put air in the balloon it's still a balloon, and when it loses air it's still a balloon. So it's a physical change since it didn't change in substance.
If you heat a bottle and put a balloon on it then apply heat from a hair dryer why does it inflate?
because heat expands things... and the heat expands the air in the bottle and the air in the balloon... the only place for the air to go, since it cannot expand the bottle... is out into the balloon, increasing the pressure there and inflating the balloon. :-)
