because the helium expands in the balloon in order to change shape
Yes, when air is blown into a balloon, its shape will change from deflated to inflated. The volume inside the balloon will increase as more air is added, causing the balloon to expand and become larger.
No, the balloons will not repel each other. Blowing air between the two balloons will create a breeze, but it will not generate enough force to cause the balloons to repel from each other.
When you blow air between two balloons of nearly equal size hanging on a stick, the balloons will move away from each other due to the air pressure pushing them apart. This occurs because the air flow creates a region of higher pressure between the balloons, causing them to repel each other.
Yes, the shape and size of a toy balloon depend on the type of gas inside. Helium makes balloons float, while air or carbon dioxide results in balloons sinking. The gas affects the overall buoyancy and volume of the balloon.
Square balloons can be made by using special molds that create the square shape when inflated. These molds are usually made of plastic or metal and can be filled with air or helium to create the square balloon shape. Square balloons are not as commonly available as traditional round balloons, but can be found at specialty balloon stores or online.
If you blow between them, you decrease the pressure of the air between the balloons. The air around them, which has greater pressure, will force them to approach each other.
no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
Gases used are: air (and hot air), helium.
The skin of the balloon is air-tight - it's simply trapping the air you breathe into it.
When you squeeze a balloon, you are applying pressure to the air inside it. This increased pressure causes the air molecules to move closer together, which changes the balloon's shape. Once you release the balloon, the air molecules move back to their original positions and the balloon returns to its original shape.
Yes, but it will be hard to do because they are generally thicker than regular balloons.
Yes, when air is blown into a balloon, its shape will change from deflated to inflated. The volume inside the balloon will increase as more air is added, causing the balloon to expand and become larger.
There are several types of hot air balloons, including traditional spherical shape balloons, special shape balloons (such as animals or objects), and solar balloons that use solar power for heating. Each type serves different purposes and offers unique designs.
No, the balloons will not repel each other. Blowing air between the two balloons will create a breeze, but it will not generate enough force to cause the balloons to repel from each other.
because it can blow up the hole balloon
if the heater does not blow out warm air change the setting.
Circles and spheres have the least amount of surface area per volume than any other shape, and so it is a very popular shape for hot-air balloons as less heat is dissipated through the skin of the balloon.That being said, hot-air balloons have been made in many different shapes.
