physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.

What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
Physical change copper chloride aluminum foil experiment?
It's a chemical change. The aluminum foil is rusting, which cannot be undone, meaning that this is a chemical change, not a physical. Physical changes can be reversed.
Is toasting bread an example of a physical or a chemical change?
Yes it is, as the browning of the bread when you toast it, is a reaction between the reducing sugar and amino acids. The reaction is called Maillard reaction. In simpler words, the bread is being "burned" which is a chemical change as it cannot be reversed. You can't get back the same soft,fluffy, white bread after you toast it.

Why physical change can easily be reversed but chemical change cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.

What is the difference between chemical and physical changes?
A chemical change is when something cannot be reversed and often a precipitate (solid) is formed. While a physical change can be reversed e.g bending a piece of wire.

What are three differences between physical and chemical changes?
(i) Physical change does not result in formation of new substances Chemical change result in formation of new substances (ii) Physical change is a temporary change Chemical change is a permanent change (iii) Physical change is reversible Chemical change cannot be reversed back (iv) e.g of Physical change-Dissolving of sugar in water to obtain a sugar solution e.g of Chemical change-Burning of sodium in chloride

Is rusting a phsyical change?
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
