Oxygen Helium

Explains:How These Gases:HYDROGEN,HELIUM,NITROGEN&OXYGEN:Can Be Obtains In It's Single Form Or Quantity ?

AGAIN , THE GASES ARE : HYDROGEN , HELIUM , NITROGEN AND OXYGEN.
HOW THE GASES CAN BE OBTAINS IN IT'S SINGLE FORM OR QUANTITY ?

Helium is a noble gas and it do not form molecule by combing two or more atoms. Helium is single atom molecule.
Single atoms of Hydrogen and Oxygen are referred as nascent hydrogen and oxygen in many texts. Hydrogen, Nitrogen and Oxygen forms molecule by combing two atoms. When Hydrogen and Oxygen are produced by electrolysis or thermal dissociation of the molecules - it is single atom for a very short period - and data are available for half life of the single atoms. Nitrogen can also be produced as single atom by thermal dissociation of Nitrogen molecule. It is easy to produce single atoms of Oxygen and Hydrogen in laboratory or for larger applications using radiation of specific wave-length.

Reasons Of Voice Crack And Effects Of Helium On Voice

When it comes to voice cracks, non-singers should worry about unlikely voice cracks because rock singers have no major issues with a cracking voice. It is understandable to know an occasional voice crack caused by surprise. Just like voice cracks, helium also changes the voice; it can be taken as a joke but one really wants to know why helium changes one’s voice.

What causes concern is the kind of voice cracking accompanied by pain, throat fluid, and a rise in body temperature. Common reasons of voice cracking are smoking, thyroid infection, cold voice, vocal cord, puberty, nodules, and colds. When it comes to helium, it is a dangerous gas to play with because breathing pure helium deprives the body of oxygen, as if one is holding the breath. This results in cutting off the oxygen supply to the brain and causes a person to collapse or perhaps suffer brain damage after that. Inhaling helium can result the body’s oxygen level to fall to a hazardous level in just a matter of seconds. It is funny to hear someone who has just gulped a bit of helium from a balloon speak with a squeaky voice. This trick is used by clowns and comedians to make audiences laugh in parties.

The voice cracks because of smoking because it taxes the vocal chords of a person. As time passes, it results in a marked cracking in their voice. Thyroid infection results in a cracked and deep timbered voice. It also interferes in the swallowing mechanism. Thyroid gland can be scanned by ultrasound. A regular strain in the vocal chords creates callous around them and when a person speaks, the voice sounds croaky and broken. People who are likely to develop nodules in their throats are preachers, cheer leaders, teachers and stage actors.  For avoiding this, vocal chords should be given rest and refrained from shouting. Voice cracking results from cold voice. Teenagers go through a rapid growth phrase that affects their voice. It’s a time when everything in them grows and develops. This is because of growth hormones and this fades away with a passage of time.

As it has been known that helium neither changes the pitch of one’s voice neither it hastens the speed of the sound of voice through air, the reason for the squeaky helium voice is something else. According to research, the reason for thesis in the resonance of the sound inside the vocal tract. Because helium is lighter than air, this makes the sound travels fast in it. Inhaling little helium fills the vocal tract with it and any sound created within travels faster than the tract is filled with ordinary air.

To avoid voice cracking, one should avoid screaming, give a rest to the voice, avoid drinking cold and hot water alternately and speak and sing naturally using one’s own voice. A cracking voice that is brought on by puberty is not avoidable; it can be avoided before it gets serious. Excessive voice cracking results in inflammation of vocal cord and it might even lead to throat cancer. Smokers can be likely infected.
