Chemical Changesthe release of gasgreater changes of heatthe generation of lighta change of colorthe formation of a precipitateThese are chemical changes because they change the substance's properties.
Not all physical changes accompanied by a chemical change. Melting and freezing are two physical changes that are not accompanied by a chemical change.
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
chemical changes change the basic chemical makeup of something, while a physical change only changes an item's appearance
no its not a chemical change its a physical change.
A physical change is a change in chemical composition. A physical change is a change where chemical composition is not altered. Not all chemical changes are accompanied by a physical change, but some are. The same is true for the reverse.
Chemical change changes the chemical arrangement and physical configuration. Physical change changes the physical configuration but not the chemical arrangement, e.g water to steam.
physical changes change the color, shape, or state of matter. chemical change is the change from one substance to another.
Physical changes are reversible, while chemical changes, for the most part, are not.
Chemical change not a physical. A CHEMICAL CHANGE
Iron is a chemical element, not a change.
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
yes, a substance undergoes a chemical change when it changes in state.
It is a chemical change. Hint: if something is a reaction it is probably a chemical change.
Changes in color, temperature changes (heat absorbed/released), and changes in chemical reactivity are all indicative of a chemical change.
Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
A chemical reaction is a chemical change.
Physical changes and Chemical changes are both the same - this would be a reversible change.
It changes properties.Physical Changes:Physical changes are changes in the appearance but not in the chemical properties. Some physical changes can be undone so the item can be put back to almost its past form.Chemical Changes:Chemical changes are the changes in chemical properties. Chemical changes also change in appearance and/or leave behind traces to prove that a chemical change occurred. Chemical changes create a new substance when they happen, e.g., cooking an egg. Chemical changes cannot be undone as the molecules, patterns and properties have been changed.How to tell them apart:The way to tell the difference between chemical and physical changes is by the changes that it went through. There may be clues that a chemical change appeared because of sound, light, gas production or an odour. A physical change does not involve any of these.

No, changes of state such as this are physical changes.
