Yongkang Pengrong Steel Cylinder introduces you to helium related knowledge

1. What is helium

Helium, the English name Helium, and the Chinese (hai) symbol for He, is colorless, odorless, non-flammable gas, and its content in the air is about 5.2 parts per million. It is chemically inactive and does not combine with other elements or compounds under normal conditions.

2. Is helium safe?

Use an open flame to burn a balloon filled with helium. The balloon will burst, but it will not produce a larger open flame or burst. The effect is the same as burning a balloon filled with air.

3. Will the sound change when inhaled with helium?

Inhaling helium gas with the mouth is generally to fill the balloon, and then hold the mouth of the balloon to let the gas run to the lungs by itself. The sound speed of helium is close to three times that of air, so the resonance frequency has also become three times. Therefore, the original fundamental tone resonance is good and the amplification is relatively large, and now the higher frequency overtone resonance is good, and the overall tone color gives people a "high frequency" feeling. But when it comes to "tone", it hasn't changed. The voice change can only last for 1 to 2 minutes. Take a big sip to change a sentence. Prolonged inhalation will cause symptoms of hypoxia.

4. Why is helium so expensive?

The demand for helium gas is very large, but the helium resources on the earth are very limited. This year, some experts predict that the helium gas on the earth may be exhausted in the next 10 years. In addition, my country's helium resources are particularly scarce and almost all rely on imports. It is conceivable that the price of helium will not be too low.
