What is lighter than air? | elements for kids | hydrogen facts | element of the periodic table | hydrogen 101 | fun facts about hydrogen | hydrogen element |. Hydrogen is a colorless and odorless gas at room temperature and pressure. hydrogen gas at room temperature and pressure is 14 times lighter than air. it is so light, it easily escapes earth’s gravity and enters space. hydrogen gas is extremely flammable when mixed with oxygen. burning hydrogen gas caused the famous hindenburg airship disaster.
Hydrogen facts for kids. the only element without neutrons. metallic hydrogen may exist in the cores of gas giant planets like jupiter. hydrogen makes up 10 percent of the human body. due to its highly flammable nature, it is dangerous. using a dilute acid and a metal, you can create hydrogen gas in the lab. the combination of liquid hydrogen. Hydrogen becomes a liquid at very low temperature and high pressure. under extremely high pressure it can become a liquid metal. it is thought that metallic hydrogen exists at the cores of gas giant planets like jupiter. around 10 percent of the mass of the human body is hydrogen. because it is so light, it was once used in lighter than air. It is even lighter than air. in fact, this substance is almost 15 times lighter than air. the lightest substance in the universe is an element known as hydrogen. an element is matter than cannot. 9. hydrogen is estimated to make up more than 90 percent of all atoms and 75 percent of the mass of the universe. [12,13] 10. hydrogen has the lowest density of all gases. [1] 11. hydrogen is approximately 14 times lighter than air. it is the lightest chemical element.
