If you blow up a balloon then the helium inside it will run out after about 2 days. After those two days (maybe 3) there will be no helium left, but you will find that the balloon is still up and rounded but not as big as before. This is because the helium had got warm inside the balloon and transfered into a liguid, then that got evaporated and turned to a gas. Therefore the gas isn't helium. Because as it changed to a liquid, the liquid picked up other parts of gas and that transfered to a liquid with it to. So it is just an ordinary gas, Oxygen. Thank You. Lucie

∙ 13y agobcoz ,,,,after reaching a certain height d pressure of d gas inside the balloon bcomes higher or larger than than the pressure outside the balloon......so the pressure inside it tries 2 come out and as a result it bursts.....

∙ 13y agoIt will stop rising when one of two things occur:
- The balloon burts because the atmospheric pressure on the outside is signifcantly less that the balloons internal pressure.
- If the former does not occur, the balloon will stop rising when its bouyant force is equalized. Because Hellium is lighter than air, it will float on top of air. Once it reaches the "surface" of air, it will stop rising.

∙ 9y agoIt is because helium is a stable gas whose valency is zero and it is in duplet state.Moreover it is nonreactive.So,when it rises up it cannot combine with other gases and it becomes stable.Thus,it stops.

What are some effects of sucking up helium?
Sucking up helium leads to a temporary change in the sound of your voice because it causes the vocal cords to vibrate faster. However, it can also cause dizziness, difficulty in breathing, and in extreme cases, it can result in asphyxiation if done excessively or improperly. It is important to use caution and not inhale helium directly from a pressurized tank.
Is a helium liquid?
No - it is a gas element

Does adding more solute to a solvent raise its freezing point lower its boiling point raise its boiling point or does not affect its boiling point?
raise its freezing point
Why do helium-filled ballons raise in air?
Because helium is less dense than air.
Why do helium-filled balloons raise in air?
Because helium is a less dense gas than a general air mixture
How much hot air does it take to raise a hot air balloon?
No set answer to that, it depends on how much the balloon has to lift.
How do you guide the hot air balloon?
You change the volume or the weight of the balloon to raise it or lower it into air currents that are traveling where you want to go.

How does thermal energy converted into gravitational potential energy?
One example would be in a hot air balloon. Heat is used to raise the balloon and the higher the balloon gets, the more gravitational potential energy it gets.

Can heat energy be converted to potential energy?
Yes. This happens, for example, when steam is used to raise something like a balloon.
How much fuel does a hot air balloon need?
Lots and lots of it! If it doesn't have enough, it will start to raise, but sink into nowhere.
