Because helium is less denser than air a helium balloon can rise; it is very simple !
A helium ballon (if it does not pop). If it does pop, then it will accelerate 10meters per second squared due to gravity.
A pop will freeze faster when it is left open, as this allows for better air circulation around the liquid, resulting in faster cooling. Closing the pop restricts air movement and can slow down the freezing process.
On modern airplanes no, because the cabin is pressurised to the same atmospheric pressure as on the ground. If the balloon was on the outside of the plane, and the atmospheric pressure at that altitude were low enough, then yes, the balloon would pop.
A helium balloon of the same material will deflate faster. Helium molecules are smaller than those in regular air, so they'll seep through tiny holes and imperfections in the skin of the balloon faster. When using the standard PIN analysis - both helium and common air balloons were found to deflate at the same rate. To the naked eye, both balloons stuck with a pin deflated with a pop. However, if the balloons are left intact, the helium balloon will deflate faster. This is because the helium molecules are small enough to pass through the rubber balloon, and they gradually leak out.
The helium weighs less than air- so when the balloon is filled, it displaces the heavier air, and floats. Just as a bit of wood weighs less than water, and floats on water. In a vacuum, a helium filled balloon would not float (but it may pop)
I think you mean HOP-UP not pop-up. It's a faster rate of fire.
helium balloons get filled with a amount of air in which is called helium it is used to make balloons float around in air. helium is a inert,gaseous element!!!!!yea i kenisha am smartHelium is less dense than air, therefore a helium-filled balloon will float in air.Helium is lighter that air, so it effectively floats on air. As a helium balloon is submerged in air, it rises upwards (like an air filled bubble in water).
For Reggae to pop you must fill it with helium and then stick it with a pin
No because you are adding cool air when you do so. It may prevent scorching, though.
The gas helium is less dense than the nitrogen-oxygen mix of atmospheric air. So a balloon filled to the same pressure (or even higher) will have a lower density than the air around it, which will displace it (flow under it), forcing it upward. The balloon will rise until the combined weight of the helium and the balloon are the same average weight (density) as the surrounding air. Long before it reaches that altitude, a normal balloon will begin to expand and will usually pop (at an altitude of a few hundred to a few thousand feet).Helium molecules are lighter than most air molecules in the atmosphere (mostly nitrogen and oxygen) therefore they are prone to rise while heavier molecules move downward.
they make the noise because all of the air that was in there comes out so fast. _ When you pop the balloon the air comes out so fast that it's faster than the speed of sound creating a sonic boom
This is because of the helium they use to blow them up. If you noticed if you blow it up with your mouth, it does not float. Helium is much less dense for a given volume than air. The air pushes beneath the balloon and forces it upward. If it reaches a point high in the atmosphere where the air is the same density as the helium, it will stop rising. However, the pressure in the balloon will also force it to expand, so it will normally pop before it gets that high. Most latex balloons will pop, and most Mylar balloons will split open, somewhere around 2,000 to 5,000 feet in the air.
