Xenon is not only an asphyxiant, it is also an anesthetic. It has been used experimentally for this purpose, but it is much too expensive for general use. So don't breathe it. If you want a dense gas to demonstrate the effect on the speed of sound (and the pitch of your voice) ...
People plant a great number of young trees in the mountains.When the trees grow big and tall enough, they are cut down by workers and carried out of the mountains to the paper mill where fine paper is made from wood.Then it is taken to every corner of the country and used for differe...
Nowadays, there remains to be afew noble gases because of the low chemical reactivity of these said gases. F. 5.because of their properties, noble gases have many importantapplications. They are widely used in medicine and industries. For instance,liquid Helium is used for superconducting ...
These noble (meaning unreactive) gases are not on the whole particularly rare substances. Helium, in fact, is the second most common element in the Universe, after hydrogen, while the air in an average sitting room contains about a kilogram of argon. The first real evidence for these ...
5. Because of their properties, noble gases have many important applications. They are widely used in recreation, medicine and industries. For instance, Liquid Helium is used for superconducting magnets(磁体). These magnets are very important in physics and medicine. When a doctor suspects that a...
