Letting gas out of a cylinder always causes a cooling. This is the Joule-Thomson effect. As the gas expands work is done against the interatomic/molecular attractions (dispersion forces for helium).
Helium is lighter than air, therefore it rises upwards.
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
because helium weighs 4u and air (80% nitrogen) weighs about 14u. because helium has less mass, it has less gravity and rises. it has also to be a gas as a substance in a gas form has a much lower density as a liquid or solid form. earlier they used hydrogen (1u), but that is highly explosive. (u is relative mass for atoms)
Most planets are not made of helium; they are primarily composed of hydrogen and helium gases, with rocky planets like Earth containing elements like oxygen, silicon, and iron. However, helium is abundant in gas giants like Jupiter and Saturn, where it makes up a significant portion of their atmospheres due to their composition and formation processes.
If we let all of Earth's helium float off into space, we will not be able to replace it. Helium is a very important resource because it can be cooled to very low temperatures and exist as a liquid. It's used in MRI machines to cool the superconducting magnets, for instance. When used for cryogenic purposes, it's allowed to boil off into the atmosphere, where it floats up into space and is lost forever.
Nope.
because earth has gas particles that can let helium go
More than likely a Helium filled balloon. A Hydrogen filled balloon is very flammable and might burst into flames similar to the Hindenburg blimp/dirigible. Helium is not flammable.
No, I am not able to physically inflate a balloon. However, I can provide guidance or information on how to inflate a balloon using a pump, helium tank, or manual blowing. Let me know if you need any instructions!

aluminium foil keeps food colder because it doesn't let air in.
If the hot water tank is off it is possible. It is also possible for the cold water going to the hot water tank to freeze. Insulate all pipes that are exposed - or let them drip (this is more expensive!)
Yes, the helium doesn't let oxygen get through to your brain and can definitly make you feel light headed an dizzy.

Let bondo air out, colder weather will make it take longer.
Well, honey, it's not the number of balloons that'll kill you, it's how you use them. Inhaling helium straight from a tank can lead to oxygen deprivation and potentially cause you to pass out or suffocate. So, let's stick to using balloons for parties and leave the risky business to the professionals, okay?
