# How do you blow up a balloon in a bottle?

## What happens to the balloon if air is blown to the plastic bottle?

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.

## Which balloon is easier to blow up the balloon inside the small bottle or the balloon inside a big bottle Why?

So the pressure inside the small balloon is greater than the pressure inside the large balloon. We experience this when we blow up a balloon: the first stage is the hardest, and once the balloon has inflated a little, the task becomes much easier.

## What happens to the balloon inside 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.

## Is blowing up a balloon a chemical change?

Blowing Up a Balloon Science Experiment Explained When the two materials mix, a chemical reaction occurs and the byproduct is carbon dioxide gas. It is the gas that causes the balloon to inflate.

## Why does inflating a balloon violate Boyle’s Law?

Boyle’s law states that volume of a gas is inversely proportional to the applied pressure. Whereas inflating balloon violates Boyle’s law because there is increase in volume with increasing pressure.

## What type of change inflating of a balloon is?

Inflating a balloon is a reversible change. When air is blown into a balloon, its shape and size change and the balloon gets inflated. Now when the air filled in the balloon is allowed to escape, the balloon comes back to its original size and shape. Hence, inflating a balloon is a reversible change.

## What causes the balloon to inflate?

Gases expand rapidly because their particles move at high speeds in all directions. As the carbon dioxide gas fills the bottle, it has nowhere else to go so it begins to fill the balloon. As the carbon dioxide gas fills the balloon, the balloon inflates.

## Why did the balloon inflate when the bottle was placed 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.

## When water is placed in the inflated balloon inside the bottle what causes it to gush out when the bottle is unplugged?

Unplugging the bottle will release low pressure’s hold on the higher pressure air inside the balloon and allow outside air to enter the bottle once again. Not only will the balloon collapse, but the water inside of it will also be propelled by the force of the air.

## What happens to the balloon when the air inside a bottle is warmed and cooled?

(Gases always expand when they’re warm – the heat gives the gas energy to spread out more). The expanding gas blows up the balloon. When you put the bottle into cold water, the air cools down again. Cool air hasn’t got as much energy, so it shrinks – and the balloon shrinks with it.

## What happens to the pressure inside the bottle when the balloon expands?

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.

## What happened to the volume inside the bottle when the large balloon was moved up and down?

When you increase the volume (the amount of room) you decrease the pressure inside that space, this law of physics is called Boyle’s Law. As the bottom balloon is pulled down, the volume increases and the pressure decreases. But, the pressures on the inside and outside of the bottle must balance.

## How does temperature affect the size of a balloon experiment?

When the molecules are moving fast under higher temperatures, they run into the sides of the balloon more often making the balloon bigger. Basically a warmer temperature leads to higher energy gas molecules which take up more space since they are moving faster.

## How do you inflate a balloon science project?

SCIENCE: When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.

## Is blowing gas a chemical or physical?

There’s no reaction. It’s a physical phenomenon. When the bubble pops, the gas inside starts to mix with the gas outside. The liquid splatters.

## What type of change is blowing of balloon and its bursting?

Inflating of balloon Bursting of balloon 1 It is a reversible change. 2. When we blow air, its shape and size changes and when air escapes out it gains its original shape and size.

## Why blowing a balloon is a physical change?

Blowing a balloon is a physical change as no new product is formed but when balloon is burst there is no new product formed but after bursting we cannot get the balloon back so it is a physical irreversible change.

## When an inflated balloon is immersed in water which law?

The theory known as Boyle’s Law states: If the temperature remains constant, the volume of a given mass of gas is inversely proportional to the absolute pressure. Suppose you had a balloon measuring one cubic foot at the surface of the water. This balloon is under 1 ATM (14.7 psi) of pressure.

## How is Boyle’s law used in everyday life?

You can observe a real-life application of Boyle’s Law when you fill your bike tires with air. When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire.

## Is deflating a balloon a physical or chemical change?

Observation: The size and shape of the balloon change on inflating and deflating, but no new substance is formed. Conclusion: Inflating and deflating a balloon are physical changes.

## What happened to the balloon placed in hot water?

In hot water, the Balloon inflated because of hot air molecules, and in cold water, the Balloon deflated because of cold air molecules. The hot air molecules are less dense in weight and tend to rise and occupy more space. That’s the reason the hot air molecules travel inside the Balloon and make it expand.

## What happens to the balloon in the bottle with cold water?

Step 5: Move the Bottle Back to the Cold Water What do you think will happen to the balloon!? You guessed it! The balloon will quickly shrink and deflate again once the bottle is placed in the bowl of cold water! This Baking Soda and Vinegar Balloon Experiment is another super cool way to inflate a balloon too!

## How do you fill a water bottle with water balloons?

You can cut the bottom off a plastic bottle to create a makeshift funnel if you need to. Use an empty soap dispenser with a pump. The bigger the better. Fill it up with water, attach the balloon neck to the pump nozzle, and squirt water into the balloon.
