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
bcoz ,,,,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.....
It will stop rising when one of two things occur:
It 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.
Because the atmosphere doesn't extend indefinitely. It gets thinner and thinner as you go up.

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.
No - it is a gas element
Raise your leg and your foot
raise its freezing point
Because helium is less dense than air.
Because helium is a less dense gas than a general air mixture
No set answer to that, it depends on how much the balloon has to lift.
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.

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.

Yes. This happens, for example, when steam is used to raise something like a balloon.
Lots and lots of it! If it doesn't have enough, it will start to raise, but sink into nowhere.
