## What happens to a balloon if you place it on a boiling 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 happens to the balloon when it is heated?

Air molecules collide into the balloon with the same energy inside and outside the balloon. When the bottle is heated, the air molecules inside start moving faster. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.

Why does the balloon inflate when the bottle is put 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 is causing the balloon to inflate?

Warm air is less dense than cold. Since warm air takes up more space than the same amount of cold air it makes the balloon inflate.

What happens if you microwave a balloon?

It’s simply the expansion of air trapped in the bottle and the balloon. Air expands when it is heated; it spreads out and either fills a larger space or raises the pressure in a closed space.

What happens to the pressure when you inflate a balloon?

When you inflate a balloon, you’re actually putting gases, in this case mostly helium, into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands… As you go higher into the atmosphere, the air becomes thinner, and the atmospheric pressure drops.

#### What happens if you inflate the balloon more?

What do you feel as you press the balloon?

You probably feel the air pressing against the wall of the balloon with even greater force. By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases.

What happens when you freeze a water balloon?

There’s plenty to learn from a frozen water balloon, starting with the patterns of bubbles—or lack thereof—in the ice. The water in an ice balloon freezes from the outside in. As the water freezes, it creates pure crystals of water, which are clear.

## How do you pop a balloon with heat?

Hold the balloon 30–50 cm over the top of the flame and slowly move the balloon closer and closer to the flame until it pops. Note: The flame does not need to touch the balloon before the heat melts the latex and it bursts.

What happens when you release the air from the balloon?

When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. As the air escapes from the balloon, it exerts a force on the ground and the air outside of the balloon.

Can a helium balloon hit a plane?

A: Yes, I have seen several weather balloons while in flight. There have been cases where weather balloons have been struck by airplanes. Usually there is no damage to the aircraft, but occasionally to the weather instruments. It’s a rare occurrence.

### What happens when you put water in a balloon?

When the bottle is placed into the pan of ice-cold water, the cold water causes the air inside the bottle to cool down. As the air in the bottle cools down, the molecules of the air slow down and take up less space because they move closer together. The air then moves out of the balloon and back into the bottle, causing the balloon to deflate.

What happens when you turn off the hot plate on a balloon?

The balloon will fill up with hot air and stand straight up. When that happens, turn off the hot plate and leave the bottle on the hot hot plate. DON’T touch the glass! It will be very hot. Use the hot pad to remove the bottle to a heat-safe location so the glass can cool. Watch what happens to the balloon as the bottle cools.

What to do when a balloon fills up with hot air?

Give the bottle and balloon apparatus a few minutes to get warm. This may take a a little while. Use a camera for pictures or even a video to study later on to check the data you collect. The balloon will fill up with hot air and stand straight up. When that happens, turn off the hot plate and leave the bottle on the hot hot plate.

#### Why do you put a balloon on top of a bottle?

By placing the balloon on top of the bottle, you trap the air inside of the bottle. This experiment is a great way to show how matter behaves when it is heated and cooled. Matter expands (gets bigger) when heated and contracts (gets smaller) when cooled.
