Is dissolving sugar in hot water a chemical or physical change?
The common sugar is Sucrose when it becomes soluble in water it is converted into Glucose and fructose on evaporating you can not get back the crystals of sucrose so it is a chemical change.
Is dissolution of common salt is chemical or physical change?
It is a physical process; on the other hand dissociation in water is a chemical process.
Are physical changes and chemical changes the same?
No. A physical change is a change in which no new substances are formed. Change of state is a common example of physical change. A chemical change is a change in which one or more new substances are formed. Thus, the main difference between chemical and physical changes is whether new substances are formed.
Is bubbling and fizzing a physical change or chemical change?
Physical. If a substance releases bubbles, it is converting some of its liquid into a gaseous state. The chemical properties do not change, only its present state. A most common physical change is that of watching ice melt in glass of water.
What are the characteristics of physical changes?
Some common characteristics of physical changes are change in texture, change in shape, and change in state. There can also be a change in temperature and a change in color, but these are also common characteristics of chemical changes. A physical change does not change the composition of the original substance.

What reactants and products of a chemical change have in common?
The reactants and products of a chemical change have nothing in common - hence the name "chemical change".
Is melting butter an example of chemical change?
Partly physical, partly chemical. Melted butter has different chemical properties than solid butter. The melting process, as with chocolate, is not reversible. Proteins in the butter can become denatured, and isomerization of lipids to trans fats occurs. Phase change is a common example of physical change, but chemical change also occurs in this case.
What do physical and chemical change have in common?
they both alter an object in some way or they both change there main object. THE CORRECT ANSWER WOULD BE>>>> there is no change in the total mass involved in the change
