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
Chemical changes involve breaking and forming of bonds between atoms. Chemical energy is required to break bonds. The formation of new bonds releases energy.
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.
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
no physical change is ptting ice cream and milk and mixing it for a milkshake or burning a piece of paper.
i know that its physical change because all you saliva is doing is making the food wet
Both transitions, from solid to liquid and liquid to gas are purely Physical Changes. There is nothing Chemical happening.
A physical and Chemical change.
Actually both physical and chemical changes are happening during cement mixing.

it is a chemical property because it changes the chemical structure of the molecules in the base
During a chemical change the molecule is transformed; during a physical change the molecule is not transformed.
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
There are no physical changes. there are only chemical changes.
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
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.
Physical Changes
becaz' it only changes in its physical appearance andno molecules are increased or decreased and no process of chemical change happen
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
