# Why does a balloon with air weigh more than an empty balloon?

## Why does a balloon with air weigh more than an empty balloon?

Because it was compressed, the air inside the balloon is denser than the air outside. You have more molecules of air in each cubic inch of space. What you have shown is not that a balloon full of air is heavier than an empty balloon.

## Which is heavier balloon with air or without?

When you fill a balloon, you have to compress it to expand the rubber. Compressed air has more weight as a similar volume of air at normal atmospheric pressure. Therefore the balloon is heavier than an equal volume of air.

## Does a balloon weigh more when it is blown up?

However, if the air is under pressure, as in a latex balloon or a rigid, fully-inflated mylar balloon, then the air under pressure in the balloon will be denser, and therefore heavier than an equivalent volume of free air. Such a balloon will weigh more inflated than deflated.

## Is an inflated balloon heavier or lighter?

The mass of an inflated balloon is higher because it contains air. Even when inflated with helium, it has a higher mass because helium has mass. However, an inflated balloon has a much lower density than a deflated balloon.

## Does air in a balloon weigh anything?

Scales say “2”. So since a balloon full of air weighs more than the empty balloon – voila: Air has weight! And that is because what you measure is not the weight of air – the same volume of air was there before you inflated the balloon anyway. What you weigh is the increase in weight as you compress air.

## What will happen when you pump air into the balloon?

Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.

## Can you fill a balloon with space?

A helium-filled balloon can float very high up into the atmosphere, however, it cannot float up into outer space. The air in Earth’s atmosphere gets thinner the higher up you go. Outer space starts somewhere around 600 miles (960 kilometers) above Earth’s surface.

## Why does balloon burst if you keep on blowing?

➡a balloon bursts when you keep blowing because the ballon has a certain capacity to withstand pressure when pressure exerted is more than it tends to inflate more than its capacity that is beyond what it can therefore at last it bursts as it can not handle that pressure.

## Can you press the balloon with your hands why or not?

1. can you press the balloon with your hands? why or why not? answer:_______________2.

## When you rub a balloon on your hair the balloon becomes charged by?

electrons

When you rub a balloon on your head, electrons move from the atoms and molecules in your hair onto the balloon. Electrons have a negative charge, so the balloon becomes negatively charged, and your hair is left with a positive charge.

## Why does rubbing a balloon on your head cause static electricity?

When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon.

## Can a balloon be positively charged?

When a charged balloon is brought near a conducting can, the electrons are pushed to the far side of the can. If another object touches the side of the can opposite the balloon, electrons flow into the other object, leaving the can positively charged.

## Why is my balloon not sticking to the wall?

Balloons don’t stick to walls. However if you rub the balloon on an appropriate piece of material such as clothing or a wall, electrons are pulled from the other material to the balloon. The balloon now as more electrons than normal and therefore has an overall negative charge.

## How do you get a balloon to stick to the wall?

When you rub a balloon against your clothes and it sticks to the wall, you are adding a surplus of electrons (negative charges) to the surface of the balloon. The wall is now more positively charged than the balloon.

## What will happen when the balloon is moved closer to the wall?

The balloon ends up with extra electrons, making it negatively charged. When the negatively charged balloon approaches a wall, the negative charges in the wall are repelled (or pushed away). This leaves a positive charge on the wallboard at the spot where the balloon touches.
