what is a liquid solution and a gaseous solution?

Do you intend to ask us to name a liquid solution and a gaseous solution.
One example of a liquid solution is vinegar. It is acetic acid in water. That is a solution of two liquids. An example of a gaseous solution is air. Nitrogen is mixed with oxygen and a few other gases. This may not be what you intended; if not, please clarify and repost.

A liquid solution is a homogeneous mixture where the solute (substance being dissolved) is in a liquid state and is uniformly distributed throughout the solvent (liquid in which the solute is dissolved). In a liquid solution, the solute particles are dispersed and mixed with the solvent particles at the molecular level.

An example of a liquid solution is saltwater. In this solution, salt (solute) is dissolved in water (solvent), resulting in a homogeneous mixture where the salt particles are evenly dispersed throughout the water.

A gaseous solution, on the other hand, is a homogeneous mixture in which the solute is in a gaseous state and is uniformly distributed throughout the solvent gas. In a gaseous solution, the solute gas molecules mix uniformly with the solvent gas molecules.

An example of a gaseous solution is air, which is primarily composed of nitrogen gas (solute) dissolved in oxygen gas (solvent), along with other trace gases like carbon dioxide and argon.

To determine whether a substance forms a liquid solution or a gaseous solution, you can consider the physical state of the solute and the solvent. If both are in a liquid state, it forms a liquid solution. If the solute is a gas and is dissolved in a gas solvent, then it forms a gaseous solution.
