WARNING: don't try this at home.
Whats happens is because the 2 chemicals don't clash, they dissolve into each other and BANG!!!! So I wouldn't try it at all. Trust me - we tried in our science experiment at school.
Before mixing you have, of course, separately sugar, water and drink mix.
sugar solution in water
it becomes a soap
boil the water, what is left in the cup is sugar
Yes, it is a physical change. The sugar seems to "disappear" in the water, but if you taste the water you will also taste the sugar. So, the basic chemical nature of both sugar and water is unchanged. That is a characteristic of a physical change.
Sugar and Salt
When a solid such as a sugar cube dissolves in water, the molecules of the sugar cube spread out and become surrounded by water molecules. The water molecules interact with the sugar molecules and weaken their bonds, causing the sugar molecules to separate and disperse throughout the water, resulting in a homogeneous mixture.
You get salt water.
They both create mixtures called solutions.
Mixing sugar and water together is a physical change because it does not alter the chemical makeup of either substance. The sugar molecules simply disperse within the water molecules, forming a homogeneous mixture without forming any new chemical bonds. This process can be easily reversed by evaporating the water to retrieve the sugar.
Physical. The water breaks up the crystals of sugar into individual molecules, but you still have sugar and water. The sugar is just in smaller clumps.
When coffee and sugar are mixed, the sugar dissolves in the coffee due to its solubility in water. This sweetens the coffee and enhances its flavor. Mixing coffee with sugar is a common way to sweeten the beverage to personal preference.
