Please answer question 2. 1. What happens when you stir a spoonful of sugar into hot water?

2. When sugar or another substance is dissolved in water, it disappears from view and forms a homogeneous mixture with the water, also called a solution.
If you can’t see the sugar, how can you tell that it is there?

You can tell if the sugar is still there by boiling the water and letting the water evaporate, and leaving the sugar behind in a container. Sugar is a solid, as we all know, so it cannot evaporate, so when the water evaporates, then you can still see the sugar.

I hope this helps, Joy!
