상품설명
Size:Small | Color:purple | Number of Items:1 At room temperature and atmospheric pressure, helium is a colorless, odorless gas. Its volume content in dry helium air is 5.24 × 10-6. Is the lowest critical temperature found by human beings. The discharge is dark yellow at low voltage. Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements. Note if large amounts of helium are inhaled, oxygen in the body will be replaced by helium, resulting in anoxia The helium needs to be excited by a high power Tesla coil or leak detector, and it will emit bright light.
