why mixing sugar and water is physical change?

Mixing sugar and water is considered a physical change because the process does not alter the chemical composition of the substances involved. In a physical change, the substances retain their individual properties and can often be separated by physical means.
When sugar is mixed with water:
1. **Dissolution**: The sugar dissolves in the water, which means that the sugar molecules interact with water molecules and spread throughout the liquid. However, the sugar itself remains chemically unchanged (i.e., the sugar molecules still consist of the same atoms in the same arrangement).
2. **Reversibility**: The solution can be reversed by evaporation of the water, which would allow the solid sugar to be recovered.
3. **No New Substance**: No new substances are formed as a result of the mixing. The outcome, a sugar-water solution, retains the characteristics of both sugar and water.
In summary, the ability to recover the original substances (sugar and water) and the lack of any chemical reaction means that this process is classified as a physical change.
