When a balloon ascends, it undergoes acceleration. This is in spite of the forces like gravity that acts on it. The acceleration of the balloon can be calculated using Newton's second law of physics.

Will a balloon with argon gas sink faster then a balloon with krypton gas?

The balloon with krypton gas has a higher density than the balloon with argon gas.


Can you explain why an inflated balloon shoots off when its air is released?

The air inside the balloon is at a higher pressure than atmospheric pressure, so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.

If a balloon is squeezed what happens to the gas inside?

When a balloon is squeezed, the volume of the balloon decreases. This causes the gas inside the balloon to be compressed, increasing the pressure of the gas.


What happened when a balloon filled with air was squeezed and gently pressed?

The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon.

What is the pressure in a balloon?

The pressure inside a balloon is determined by factors such as the amount of air or gas in the balloon, the volume of the balloon, and the temperature of the air or gas inside. As more air or gas is added to the balloon, the pressure will increase. Conversely, if air or gas is released from the balloon, the pressure will decrease.


What happens to gas in a balloon when that gas is heated?

When the gas in a balloon is heated, its temperature increases, causing the gas molecules to move faster and collide more frequently with the walls of the balloon. This increases the pressure inside the balloon, which causes the balloon to expand as it attempts to accommodate the increased volume of gas.


What was the helium balloon balloon made of?

It was made out of the light gas gas Helium.

Is a heilum balloon a gas-liquid mixture?

No, it is a gas-solid mixture when view as a whole. It has a solid component (the balloon itself), and a gas component (the helium)


Is inside balloon solid liquid or a gas?

Inside a balloon there is gas. This gas is normally helium if you want the balloon to fly high, but hydrogen also works.
