Sometimes it's not obvious, but gases have weight. The weight of all the air above you is called the barometric pressure. Each gas has a different weight. Hydrogen is the lightest gas so it floats on heavier gasses, just as wood floats in water. Helium is also lighter than air. That's why balloons are filled with helium, so they float in the air.
A balloon filled with hydrogen gas floats in air because hydrogen is lighter than air. The buoyant force acting on the balloon is greater than the gravitational force pulling it down, allowing it to float.
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
Hydrogen is less dense than air, ergo it floats. Air is of the same density as air, but the rubber skin around it makes it more dense, ergo it sinks.
Hydrogen is less dense than air, so it creates a buoyant force that causes the balloon to rise. This is because the density of the hydrogen inside the balloon is lower than the surrounding air, making it lighter and causing it to float upwards.
no it will not. because a balloon filled with hydrogen floats only because it is lighter than air so when there is a vacuum it will not float. it is like oil and water if there is no water oil is on the bottom if there is water it is on the top.
If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
A balloon filled with a gas less dense than the surrounding air, such as helium or hydrogen, rises because of the principle of buoyancy. The lighter gas inside the balloon creates an upward force that is greater than the weight of the balloon itself, causing it to float upwards.
A balloon filled with hydrogen rises until it reaches a level in the atmosphere where the air pressure outside the balloon is equal to the pressure inside the balloon. At this point, the balloon stops rising because the difference in pressure is no longer enough to overcome the force of gravity pulling it downward.
A balloon filled with -2 degrees Celsius air will move to a room to a temperature of 8 degrees Celsius because of the collision of the air particles.
The speed of the particles inside the air-filled balloon increases as the temperature increases. This is because higher temperatures provide more thermal energy to the particles, causing them to move faster.
As the balloon rises in the atmosphere, the air pressure decreases while the internal pressure of the hydrogen-filled balloon remains constant. This causes the pressure difference to increase, putting more stress on the balloon's material until it eventually pops due to the increased pressure difference.
Its filled with gas because certain gases(Helium, Hydrogen) are lighter than air so they float. That's why the balloon floats.
