The states of matter(e.g.,liquid,solid,gas)arephases, butmattercan exist in different phases yet remain in the same state of matter. For example, liquidmixturescan exist in multiple phases, such as an oil phase and an aqueous phase. The termphasemay also be used to describe equilibrium s...
Everything in the universe is made of matter, which can be described as any substance having mass and volume. The matter exists in three fundamental phases: gas, liquid, and solid. Apart from these, the matter can be either a pure substance or mixture. A pure substance is made up of on...
While the initial phase of solute and solvent may differ, the final solution always has one phase (gas, liquid, or solid). Also, the physical properties of the solution, such as its boiling or melting point, may differ from those of the individual components. All in all, a homogenous mi...
Homogeneous mixtures can be solid, liquid or gas, but in order to be homogeneous, or form a solution, they must be of uniform state once mixed. Homogeneous mixture can be formed in many ways. Sometimes a gas can dissolve in a liquid like in a carbonated drink where carbon dioxide is ...

Remember, we defined the word “phase” as being one physical state, whether solid, liquid or gas, that, well, that has distinct boundaries and uniform properties. So, homogeneous mixtures, what are they? OK, the prefix homo means “same”,so a homogeneous mixture is the same throughout;...
Homogeneous mixtures have a uniform composition and phase throughout their volume, while heterogeneous mixtures do not appear uniform and may consist of different phases (e.g., liquid and gas). Examples of types of mixtures defined by particle size include colloids, solutions, and suspensions. ...
As homogeneous mixtures, solutions have three distinguishing characteristics: They are composed of a single phase (solid, liquid, gas) The dissolved substances (solutes) are mixed with the solvent at an atomic or molecular scale The solute is uniformly distributed throughout the solution A range of...
