Yes sugar in water is a temporary change as
1) It is reversible as when we evaporate the solution/mixture it-the sugar remains behind.
2)Energy is niether evovled nor absorbed during this change
No, it is a physical change. A chemical reaction involves changing a molecule(s) into something else. When dissolving sugar in water, you still have sugar and you still have water.
There are three processes that take place in the water cycle:EvaporationCondensationTranspiration
Most evaporation on Earth takes place over the oceans due to their large surface area. The sun's energy heats the water, causing it to evaporate and form clouds, which then release precipitation over the Earth's surface in the water cycle.
Sugar water is a true solution.
it takes about 6 hours
No, dissolving sugar in water is a physical property because it does not change the chemical composition of either the sugar or the water. The process involves breaking the intermolecular forces between sugar molecules, allowing them to mix with water molecules.
In evaporation, the surface of the water begins to change from a liquid to a gas.
its as physical change as no reaction takes place. the sugar fills in the gaps between the water molecules so you cant see it un till you filter or dissolve the coffee.
Water changes phase.
Physical
Dissolving sugar in water is a physical change, not a chemical change. The sugar molecules are still the same chemical substance before and after dissolving; they have simply spread out in the water. The sweet taste comes from the sugar molecules interacting with your taste buds, not from a chemical change taking place.
Oxidization
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.
A phase change.
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 water can change from vapor , steam , etc.
It is a physical change. Frozen water ... ice ... is still water. Boiling water ...steam ... is still water. No chemical change takes place in either case.
