Dissolving sugar in water is a physical change. You can tell this because if you were to dissolve the sugar in water and then let the water evaporate, the sugar would still be left. All of the components that you started with are still there, even if you can't see them.
A physical change is a change of matter that does not alter the chemical properties of that matter. A chemical change is when bonds are broken and new bonds are being formed between different atoms.
Chemical Change: Baking soda and vinegar fizzing and creating bubbles
Physical Change: When water freezes, it doesn't create a new substance. Ice is still H2O just in a solid form.
The change is physical because the change is reversible. Evaporate the water and you are left with the sugar, no new substances are produced; the sugar stays sugar and the water, water.
The sugar cube dissolves in the water. This is a physical change, because the sugar retains its chemical structure, and when you boil off the water or remove it by another change, you are again left with sugar.
The combination of sugar and water is a physical change as you can evaporate the water which would then leave behind sugar. It is reversable so it is a physical change.
It is a physical change. The sugar does not break down chemically.
Mixing sugar and water is a physical change, because the chemical compositions of the sugar and the water do not change.
Mixing sugar and water is in fact a physical change.

It's chemical because the iodine turns black instead of its usual red-purple color
you don't make any new substances, the sugar is just mixed very well into the water
It is a physical change. The sugar is still sugar after it is pulverized.

This is a physical process.
No, mixing sugar and chocolate is not a chemical change. It's a physical change.

A chemical change involves a change in a substance's chemical make-up or conversion to a different substance. A physical change is one that involves changes in a substance's physical makeup that is not brought about by a chemical change, such as sugar dissolving in water. Therefore, mixing milk and chocolate syrup is not a chemical change. Now, if for some reason the syrup had a strong enough acid in it, and mixing the two made the milk curdle or solidify, then yes, it would be a chemical change.

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.
First and for most, sugar mixing in water is not a chemical change. It is a physical change (Something which can be gotten back) Water and sugar, once mixed, can both be seperated by heated the liquid. The water evaporates, thus the sugar is left behind. Hope i helped. Chao!

Physical. The sugar is only held in suspension. The basic reasoning behind this is that you have to stir the sugar in to get it mixed into the lemonade. A chemical change would have been generated just by mixing the chemicals together and given some type of reaction.(Heat, smoke, light, etc) You don't get a "bang" by adding sugar to lemonade. :-)
