nothing happens or in other words, nothing happens to the molecules. the only change, is in the way they move closer and furthuer from each other.
pretty much it make change in look slightly but it is still in the same substance. it may change its state of matter

Changes of state are considered physical changes because?
Physical changes are changes that don't change the structure of the individual molecules. Though heating a liquid to a gas will change how the molecules are bound to each other, the individual molecules will not change. This is contrasted from a chemical change, where the atoms of the molecules are rearranged.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.

it is a chemical property because it changes the chemical structure of the molecules in the base
What are the differences betwen physical and chemical changes in terms of what happenes to molecules?
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.

There are no physical changes. there are only chemical changes.
Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
When cooking a piece of bacon is that a physical or chemical change?
Frying bacon is a chemical change. In addition to simply heating the bacon, frying it causes certain molecules to react and change. For instance, some protein molecules may be broken down. This is why cold fried bacon tastes different than cold raw bacon.
Are state changes chemical or physical changes?
Physical Changes
Why is making a figure from lump of clay considered a physical change?
becaz' it only changes in its physical appearance andno molecules are increased or decreased and no process of chemical change happen
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
