Are Light Gases Such As Helium And Hydrogen Found?

Are Light Gases Such As Helium And Hydrogen Found? Exosphere: Outermost layer of Earth’s atmosphere that is located above the thermosphere and contains light gases such as helium and hydrogen. Why hydrogen and helium gases are rarely found in the Earth atmosphere? The atmospheric temperature was very high at the time of formation of the

What Determines How Fast Or Slow Molecules Move?

What Determines How Fast Or Slow Molecules Move? The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. The oxygen and nitrogen molecules in air at normal room temperature are moving rapidly at between 300 to
