What happens if you put a balloon underwater?
When an air-filled balloon is placed underwater, the water (which has higher pressure than the air) exerts a force on all sides of the balloon. The deeper the balloon is taken into the water, the greater the pressure, and therefore, the smaller the balloon will become.
What happens when a balloon filled with air is placed in a large bucket of water?
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.
Why does air compress under water?
Descent – As a diver descends, the water pressure around him increases, causing air in his scuba equipment and body to occupy a smaller volume (compress). Ascent – As a diver ascends, water pressure decreases, so Boyle’s Law states that the air in his gear and body expand to occupy a greater volume.
Why does a balloon filled with cold air sink in water?
The balloon will rise. Conversely if the air inside is cold high density air, it weighs more. Gravity is stronger than the upward pressure difference force and the balloon sinks.
What causes air to leave a balloon?
The collision of these air particles with the walls creates a high-pressure environment inside the balloon relative to the atmospheric pressure around it. This is why when a balloon is released, the high-pressure air flows out of the balloon to the low-pressure air surrounding it: “Winds blow from high to low.”
Does an empty balloon float in water?
If you fill the balloon with air instead of helium the mass of the balloon and the air in it is more than the same volume of air. In other words the density is more than air so the balloon sinks in the same way that a stone sinks in water.
Why does a gas filled balloon float in the room?
A gas balloon is a balloon that rises and floats in the air because it is filled with a gas lighter than air (such as helium or hydrogen).
Can helium balloons move on their own?
r/NoStupidQuestions They are very light, so even slight changes in air pressure (caused by temperature variations or your movement in the room) that you cant necessarily perceive can cause them to move.
