## What happened to the balloon when you placed the bottle in hot water?

WHAT IS HAPPENING? When you stretch the balloon over the opening of the bottle, all of the air is trapped inside. Putting the bottle in hot water causes the air molecules inside to heat up and begin taking up more space (thermal expansion), causing air to enter the balloon and inflate it.

## What is the reason why the balloon can’t be blown in the first bottle but when transfer to a bigger bottle it can be?

When a balloon is placed inside the bottle, it will not inflate, since the bottle is already filled with air particles with no escape route. This is a great demonstration that air takes up space. The air inside the bottle compresses a little bit but not enough to permit the balloon to inflate.

What happens when you mix vinegar and baking soda in a balloon?

When vinegar and baking soda mix, they create the gas carbon dioxide and water. The carbon dioxide has no where to go, but into the balloon – blowing it up. This is because the colder temperature causes the reaction to take place more slowly, releasing the gas less effectively.

### Why does the balloon expand in hot water?

Explanation: The hot water causes the air inside the bottle and balloon to also heat up. The faster moving particles inside the bottle start to move faster and faster and soon they expand to fill the balloon.

### What keeps a balloon from expanding?

Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon’s inner walls. It is those collisions which keep the balloon inflated. As the molecules heat up, they move faster and strike the inside wall of the balloon harder.

What do you observe as you push up the balloon Why?

As you push up the balloons air exerts a pressure on the wall of balloons. Simultaneously, the air present “outside the balloon” also exert the pressure on inside air. When we push the balloon, the external pressure increases push up the air inside and it will go out from it. Hence the balloon will be deflated.

#### What happens as you pull down the balloon?

What happens as you pull down the balloon at the bottom of the model? As the balloon at the bottom of the model was pulled down, the diaphragm contracts and moves down and the chest cavity expands. There is more space and less pressure inside the lungs. There is now less space and greater pressure inside the lungs.

#### Why does a balloon inflate when air is blown into it?

When the number of molecules increases, they start to collide with each other. Due to these collisions, many molecules take place near to the wall of the balloon. This initiates a high pressure on the walls of the balloon. Thus, the balloon gets inflated when it is filled with air.

Why do balloons inflate when on a bottle of hot water?

As the air in the bottle heated up the air molecules began to move faster and take up more space. The air from the bottle them moved into the balloon and caused it to inflate. When the bottle is removed from the hot water, the balloon stays inflated. This is because the air molecules in the bottle are still hot.

## Why does the balloon inflate into the bottle?

This is because the high pressure air in the balloon pushes outward harder than the low pressure air in the bottle. The air in the balloon pushes out against the walls, keeping it inflated. When the hole is unplugged, air flows back into the bottle. The air pressure in the bottle increases and collapses the balloon.

## Can you blow a balloon inside a bottle?

In order for a balloon to blow up, you must force air inside it. However, when you try to blow the balloon up inside an “empty” bottle, you can’t because the bottle is actually already filled with air!

What is the balloon experiment?

The two-balloon experiment is a simple experiment involving interconnected balloons. It is used in physics classes as a demonstration of elasticity . Two identical balloons are inflated to different diameters and connected by means of a tube. The flow of air through the tube is controlled by a valve or clamp.
