If I mixed sugar and sand into the water,what would happen? The sugar would ___, and the sand would ___

dissolve;not dissolve

Rather than asking us, I suggest you do this simple experiment yourself.

Hot or cold water??

If you mix sugar and sand into water, what would happen? The sugar would dissolve, and the sand would not dissolve.

To understand why this happens, we need to think about the properties of sugar, sand, and water. Sugar is a soluble substance, which means it has the ability to dissolve in water. Sand, on the other hand, is insoluble, meaning it does not dissolve in water.

When you mix sugar into water, the sugar particles come into contact with the water molecules. The water molecules are polar, which means they have a positive and negative end. The positive end of water molecules is attracted to the negatively charged oxygen atoms in sugar molecules, and the negative end is attracted to the positively charged hydrogen atoms in sugar molecules. This attraction between water molecules and sugar molecules causes the sugar to break down into individual particles, creating a homogeneous mixture.

On the other hand, when you mix sand into water, the sand particles do not have the same attraction to water molecules as sugar does. The sand particles are much larger and do not easily break down into smaller particles when in contact with water. Therefore, the sand remains as solid particles suspended in the water, creating a heterogeneous mixture.

In conclusion, the sugar would dissolve in the water because it is soluble, while the sand would not dissolve and would remain as solid particles in the water.
