Liquid helium is colder than anything else on the face of the Earth. They cool the magnets with helium so the wire they're made out of will superconduct - flow electricity with no resistance. The LHC's magnets use 1.5 million watts of power all tolled; imagine how much they would need if the wire had even a thousandth of an ohm per meter resistance!
What else can I help you with?
How does helium impact human life?
Helium is a chemical if you breath that chemical through a balloon or anything that involves helium will shut your body off.Helium can be a very dangerous chemical Helium is an inert gas, and despite the fact that some inhale it to change their voice temporally, I don't suggest inhaling. You need gas exchange to live.
What equipment do you need to break up molecules?
Hadron Collider - high powered electromagents in a ring, orientated so that they accelerate the particle (typically a neutron) at the molecule you want to break up (this might have to be repeated several times depending on the size of the molecule). This will most likely break apart the molecules as well as the atoms though... (depending on the velocity of the particle.) Hydro-carbon: heat is best, therefore Bunsen Burner, Furnace or High Powered Lasers etc. Electrolytes: use electrolysis, therefore two conductive rods (typical carbon) connected to a power supply, of which you have to melt/dissolve the material beforehand.
Is the Large Hadron Collider safe?
The LHC is for the most part absolutely safe. No need to worry about it causing Doomsday anytime soon. Though they say it could cause a micro black hole that would only exist for one-millionth of a second. Possibly it can create Antimatter that reacts to Normal matter. I also have read that it could create particles called Strangelets which is matter that will turn what ever it touches to its self and so on until all matter around it is a form of its self. Luckily for us the possible Black hole will not be around long enough to even tell (unless they are actually able to pick up the radiation it produces with a sensor and prove that it came from a subatomic black hole). Antimatter can be contained within a vacuum so it has no ability to react with normal matter; and Strangelets are only a scientific theory.
What materials are needed to make a model airship?
You will need cardboard or balsa wood for the frame and gondolaÊof the airship. For the blimp itself you will need a mylar bag or some other kind of nylon material, as well as helium.
What do you need to keep a snail alive?
you need food they eat rotten fruits. for its habitat you need a large inclosure give them some heat occaonaly. there you go.
Is the Large Hadron Collider dangerous?
I assume you are asking about the myth that somehow the LHC will create a singularity (black hole) and ,for lack of a better word, absorb the solar system. In which case the answer is no the LHC is perfectly safe, However there are always risks with any high energy particle experiments, radiation and high magnetic fields are of course a by product of the project, though there is no need to worry about any of those phenomena as they are safely contained and shielded
Why do starts need helium?
stars* and they don't need helium they make helium from hydrogen using nuclear fusion omg im 13 and i know this
Why does your body need helium?
Your body does not need helium. Helium is an inert gas, and it is not found as a "building block" of any organic material, or any other materials for that matter.
What is helium ions?
Helium ions can be synthesized by removing electrons from a helium atom and it would need a tremendous energy.
How many helium balloons would you need to fly in the house?
The number of helium balloons needed to lift a person will depend on the person's weight. On average, it takes about 3-5 large helium balloons to lift 1 pound. For example, to lift a 150-pound person, you would need roughly 450-750 balloons. It is important to consider factors like air currents and ceiling height when attempting to lift objects with helium balloons indoors.
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
What is a magnet used for in science?
Ooh, lots of things. Magnets are used everywhere. Electric motors use both permanent magnets and electromagnets made by electric current, for instance. The most impressive and scary use for magnets in science is in Linear Accelerators like the one at the Large Hadron Collider in Switzerland and France. Here, huge, scary magnets, magnets that need to be cooled with liquid helium to within 2 degrees of the coldest temperature that can exist, anywhere in the universe, control a pair of beams of tiny particles and make them travel at 299,792 km per second, or just a tiny bit slower than light itself. At that speed they make the two beams collide with each other. From what results from these collisions, they hope to find out, for instance, what makes stuff heavy, and find out more about how the universe works.
How much helium would it take to lift 2000lbs?
to lift 1 kg or 2 pounds you need 0.16 kg of helium so for 2000 pounds you need 160 kg of helium or 320 pounds at 1 atmosphere
Do you need helium to make a balloon float?
Yes.
What is reverse chronological causation and how does it relate to the Large Hadron Collider?
I am only answering this question because the concept is absurd and therefore amusing. You are referring to the idea presented (purely in jest, I think) that the LHC succeeds in creating a particle (the so-called "God particle") so abhorrent that a causal path from the future is created to prevent the LHC from doing this. A couple of problems here: If the LHC creates the particle, then it wasn't prevented from doing so. If it does not, then it does not, and no one need resort to time-travelling in order to explain it. Look, the LHC has had malfunctions created entirely by design flaws (Remember those? They're man-made, just like the LHC itself.) It's important to remember that people build things, and if they're as complicated as the LHC is, there is no need for nature to send back "screw-it up" particles from the future. We are perfectly capable of screwing stuff up ourselves. As evidence, I offer the fact that they recently found a piece of a baguette in an LHC magnet. Particle from the future or someone on their lunch break?
How many moles of Helium are in 6.46 g of Helium?
Helium is 4g/mol, so 6.46g of helium is 6.46/4=1.62 moles He.
Can helium be used in hot air balloons?
YES!!! However, there is no need to heat the helium. It is a light gas. and it is an inert gas.
