WebWrap Up How do chemists keep track of the number of gas particles? • Avogadro’s law states that equal volumes of gases contain the same number of particles if they are at the same temperature and pressure. This holds true for all gases. • Gases are often compared at a standard temperature and pressure of 1 atm and 273 K. This is also referred to as STP. WebThe sun is essentially a giant ball of hydrogen and helium gases. Hydrogen occurs naturally on earth only in compound form with other elements in liquids, gases, or solids. Hydrogen combined with oxygen is water (H 2 O). Hydrogen combined with carbon forms different compounds—or hydrocarbons—found in natural gas, coal, and petroleum.

WebMay 7, 2015 · At 200,000,000 °C the helium atoms in the core fuse to form carbon atoms. The last of the hydrogen gas in the outer shell is blown away to form a ring around the core. This ring is called a planetary nebula. When the last of the helium atoms in the core are fused into carbon atoms, the medium size star begins to die.
