The solubility of gases is not constant in all conditions. If temperatures differ, the solubility of gases differ. Additionally, the solvent (the substance that is mixed with a gas to form a solution) can affect the solubility of a gas (its ability to become dissolved and in turn contribute to a formed amount of concentration).
The solubility of a gas is dependent on temperature. An increase in temperature results in a decrease in gas solubility in water, while a decrease in temperature results in an increase of gas solubility in water. To comprehend this phenomena one must consider the two processes that occur when a non-polar gas is added to water. Initially a type of cavity develops when adding the solute to the solvent, representative of the conformation and overall size of the added gas, and in turn a successive process occurs in which attractive forces between the gas and water molecules are stimulated. It is this dual process that induces the water to produce both attractive and repulsive forces. By examining the water on a microscopic level and the components of the water that portray propinquity to the non-polar gases, temperature dependencies become observable.

Explanation:
These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.
The first is the electron's energy level or "shell", used as n. (Principle QN)
The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)
The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)
The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)
