Will a balloon filled with NH3 sink or float in air?
A balloon of pure nitrogen would float in air (and even rise slowly), because it has the same volume as a mole of air, but weighs less. It probably would not be very practical to make an actual pure-nitrogen balloon, but it could be done….Other Airship Gases.

What can you put in a balloon to make it float?
The density of hydrogen gas is 1/2th of the mass of helium gas so we can consider it to make a floating balloon. Air can also be used to fill the balloon.
Will a balloon filled with hydrogen float?
The balloon has to displace some air, so in response, the air pushes up on it. But hydrogen is less dense than air, so the air pushes up on the balloon harder than gravity is pulling it down, and the balloon tries to move up! So just like wood float on water, hydrogen balloons float on air.
What makes a balloon sink?
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.
Why does the balloon inflate 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.
How do you stretch a balloon over a bottle?
Simply cut the bottom off an empty plastic bottle with a pair of scissors. Then, cut a balloon in half and then carefully stretch it over the bottom half of the bottle. Next, light an incense stick and quickly blow it out. Put it inside the bottle and let it fill with smoke.
Why does the balloon start blowing up?
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 a balloon inflate in hot water and deflate in cold water?
Why does a balloon inflated in hot water and deflate in cold 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.
Why does a balloon filled with hydrogen float?
Hydrogen is lighter than air. The upthrust or buoyant force acting on the balloon filled with hydrogen gas is more than its weight. So it floats in air.
Can you set helium on fire?
As we mentioned above, helium gas is not flammable. It is not explosive either. You can heat it up or cool it until it turns to a liquid (at below absolute zero) and it still won’t catch fire. Helium is one of the most stable elements, which means that it is not very reactive with other elements.
How long can I keep a helium canister?
A: You can store helium for 6 months after opening the tank the first time. Q: Is it dangerous to breathe in helium? A: Yes it is!
How long will a foil helium balloon last?
Foil Balloons – Foil balloons hold helium well as they are non porous, the helium usually escapes from the valve over time rather than the surface of the balloon. Because of this foil balloons have a long float time and can last for 2 to 3 weeks or more.
