BIO gas
Atmospheric gas varying with concentration is ozone. It has different concentrations throughout.
The gas in regular air is primarily nitrogen, which makes up about 78% of the atmospheric composition. Oxygen is the second most abundant gas in air, with a concentration of around 21%. Trace amounts of other gases such as argon, carbon dioxide, and helium are also present.

The gas and plasma phases have a variable volume.

It never was - Nitrogen is the "major gas".
The atmospheric lifetime is important because it helps to determine the long-term impact of the greenhouse gas. If there are efficient environmental removal mechanisms for a greenhouse gas (that is, if it has a short atmospheric lifetime) the gas will accumulate in the atmosphere more slowly than predicted by the rate at which it is emitted. If a greenhouse has a longer atmospheric lifetime, then even though not a lot of it is emitted from various sources, the atmospheric concentration of the gas will continually increase, allowing the gas to contribute to global warming for a long time.

The variable gases are are those atmospheric gases whose concentrations vary through time. The variable gases are sometimes called the "minor gases" because they make up such a small percentage of the atmosphere by volume.. Carbon dioxide, methane, and water vapor are examples of variable gases.
Water exists in our environment as a liquid gas and solid.
