Give an example of a 2 phase mixture and describe how you would separate the substances

First, we should define what a mixture and a two-phase mixture mean.
A mixture is a combination of two or more substances without any chemical reaction occurring between them. Components of a mixture can be separated using physical methods such as heating, filtering, evaporation, etc
A two-phase mixture is a type of mixture that contains two different phases of matter, for example solid and liquid phases in one mixture or liquid and gas phases in one mixture.

Now, we can give examples of two-phase mixtures and mention how to separate them:
A mixture of sand and water is considered a two-phase mixture (sand is sold and water is a liquid).
The components can easily be separated using filtration where the sand will remain on the filter paper and water will pass.

Another example is a mixture of sugar and water (sugar is a solid and water is a liquid).
The components can be separated by heating. We can eat the mixture until water evaporates and the sugar is precipitated. The evaporated water can then be condensed into a different container.

Hope this helps :)
