## 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.

## Can you inflate a balloon underwater?

Learn more physics! is it possible to inflate a balloon with air underwater? A: Sure, if you have a pair of strong lungs or an air hose. The deeper the water the more pressure you would need since the underwater pressure increases rapidly as a function of depth.

## Why does a balloon filled with helium gas go up if it is not held down?

The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the weight of the helium plus the balloon fabric is lighter than the air it displaces, the balloon will float in the air. It turns out that helium is a lot lighter than air.

## Do foil balloons float with helium?

A standard foil balloon measures 18 inches in diameter (round, heart and square) or 20 inches (star) and will float with helium. Anything less than this is unlikely to float, especially if it is a shaped foil.

## Can I fill air in helium balloons?

Most balloons can be filled with helium or air, simply check the instructions provided or on the product page for details. Some balloons can only be filled with air due to their size (like mini latex and foil balloons), and some balloons are not designed for helium (like balloon garlands).

## Does vinegar and baking soda filled balloons?

a. 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.

## Why does helium make your voice high?

The human voice is made up of many different tones mixed together. “When your vocal cords vibrate, they don’t just vibrate at a single frequency, there’s a whole mix going on,” Das said. Inhaling helium makes the higher-pitched tones resonate more in the vocal tract, amplifying them so they are louder in the mix.
