A gas is a collection of atoms (and perhaps molecules) moving about in space and sometimes hitting each other. The gas is hot because of the movement energy of the atoms and molecules it contains -- the faster they move the hotter the gas.
The young Universe was filled with a gas of hydrogen and helium atoms. |
