a particle of hellium is small enough to fit in between the molecules of latex (or whatever the balloon is made of) and eventually leaks out due to diffusion. If the environment the balloon is in has the same amount of hellium in it as the balloon, it won't deflate.
The first part of the explanation is understanding why a balloon changes when you put air into it. Before you blow up a balloon, you can see that the volume is small and that the balloon is elastic. As you put more air into the balloon you are increasing the pressure. The air is packed in tight, so it attempts to push out and escape, so the balloon's surface stretches until a balance is reached. The tension of the balloon's surface combined with the outside atmosphere's pressure matches the internal pressure of the air. This equilibrium is always held. If you increase the pressure (putting more air into the balloon) the balloon's surface gives just enough so that you equilibrium is reached again. It is this maintaining of equilibrium that answers your question. If you try and decrease the volume in one area of the balloon, the air is going to push out another area of the balloon to make up for the lost volume. The volume is always maintained and the pressure remains constant.
The air in the balloon is under higher pressure than the air outside the balloon. It wants to equalize.
It's buoyancy - the same as a ship floating in water.In this case the volume of the balloon must weigh less than an equal volume of air.(That's done by using a lighter than air gas - hydrogen, helium, or just heated air.)
They can drop weight over the side, increase the hot air volume, or both. A hot air balloon will rise when its buoyancy exceeds its weight. So the balloonist can increase the buoyancy by increasing the amount of hot air contained in the balloon. Or they can simply reduce the weight of the balloon, including the gondola, its contents, and contained hot air.
Satellites are traveling at less than escape velocity. (roughly, orbital velocity is about 7 tenths of escape).
If I remember correctly, an escape of CO2
When you prick a balloon, the air inside the balloon will quickly escape through the hole created by the prick. This rapid release of air causes the balloon to pop or deflate depending on the size of the hole and the force of the air escaping.
When a balloon is inflated but not tied at the end, releasing it causes the air inside to escape quickly, creating a force that propels the balloon forward. This is due to Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction.
Sleep is vital to your body. if you don't get enough, your body will eventually shut down. actually, its kind of like a balloon, an air filled balloon. sleep is the actual balloon, and the air is your energy, if your sleep, (outer cover of the balloon) is gone somehow (puncture in the balloon) your energy (air) is going to escape. get it??
The air pressure inside the balloon is higher than the surrounding air pressure, causing the air to escape rapidly. This creates a force that propels the balloon in the opposite direction, making it fly away.
Air can escape from the ballons even if there aren't holes in them.
To bring a hot air balloon lower, the pilot can release hot air by pulling a cord that opens the top of the balloon envelope, allowing the heat to escape. This causes the air inside the balloon to cool down, which decreases the overall lift and brings the balloon closer to the ground.
The parachute valve at the top of a hot air balloon is used to release hot air from the envelope to control the descent rate. By opening the parachute valve, the pilot can allow hot air to escape, which cools the air inside the balloon and causes it to descend. This helps in maneuvering and landing the balloon safely.
Deflate is to allow air to escape from a balloon.
A small amount of air or helium within the balloon will escape through the balloon material.
The air would escape through the mouth causing the balloon to DEflate
Air can escape from a balloon even when it is tied due to the gradual seepage of air molecules through the rubber material of the balloon. Over time, the pressure inside the balloon decreases as air leaks out, causing it to deflate.
