A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.
SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.
yes
a physical change is reversible but a chemical change is not
or
a physical change is a change in which no new substance is formed; a chemical change is were one or more substances are formed
Physical change is when something simply changes its appearence, shape, or/and size. For example, if I cut up a piece of paper, it's still paper, right? If a t-shirt shrunk in the washer, it's still a t-shirt.
Chemical change is when something happens to an object and you can't change it back. For example, if you burnt some wood, it's gone. Once you burn it all, it turns into smoke. That's chemical change.
Hope this helped.
A physical change can be easily reversed, and no new substance is formed from it. The state of matter is usually changed.
e.g. ice cube melting
A chemical change cannot be reversed, and a new substance is formed. The change is at a molecular level - bonds between atoms are broken and new bonds are formed between different atoms (a rearrangement of atoms).
e.g. metal rusting
What differs Physical change from Chemical change is that a physical change is a change in state of matter, cutting, etc. But it does not make a new substance. A Chemical change is whenever something burns, tarnishes or if you mix 2 substances and get a new one, that is a chemical change. hope that helps.
the difference is that : A physical change is a change in which no new substance is formed; a chemical change results in the formation of one or more new substances. Again, consider the previous examples: Freezing water into ice just results in water molecules which are 'stuck' together - it's still H2O. Where as burning wood results in ash, carbon dioxide, etc, all new substances which weren't there when you started.
OR
A physical change is reversible, a chemical change is not. For example, the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't 'unburn' it .
Physical changes are those that do not change the chemical identity of a substance. Examples include changes of state, shape, and size. Chemical changes, on the other hand, involve the breaking and reforming of bonds between atoms. In this process, different chemical identities are formed. For example, a chemical change occurs when metals rust; this is an example of oxidation.
A physical change occur when the molecular structure of chemicals are not changed.
A chemical change occur when the molecular structure of chemicals is changed.
Grinding is physical, neutralization of an acid is chemical.
A physical change is where the individual elements are not changed, but a chemical change is where a new substance is formed.
physical changes can be not permanent like solid-liquid-vapour
chemical changes are permanent if not reversible
During a physical change the chemical composition is not changed.
Hi ez
a physical change can be reversed but a chemical changes is not. you can all tell the different from a physical and chemical change by seeing if the color or if the substances is still in it normal element and it a chemical change if it has been change to a new substances like a burn paper change to Ashes. It is all most a physical change but it can not be reversed back.
Evaporation, Condensation, Melting and Freezing are all physical changes as only the state of matter is changing, rather than the chemical properties.
Thickness is a physical property without any relation with chemical composition or chemical changes.
This is a very broad question since there are many different kinds of mixtures, and many different ways to form mixtures and to separate mixtures. In general, if you add two or more liquids (gin and vermouth) to a single container and stir, they will mix, although there are some which don't mix and instead form layers (oil and water). Separating is usually harder than mixing, because with mixing, entropy is on your side, and with separating, you are fighting entropy. Systems tend to be come more disorderly, and hence mixed. However, many techniques exist. Distillation is a process by which you boil away a substance that has a lower boiling point than some other substance with which it is mixed.
Magnetism is a physical property because attracting something to a magnet does not change the substance (change of the composition) itself and doesn't involve chemical reactions. The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, the magnetism doesn't change the substance itself.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.

While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes

Boiling is a physical change, not chemical.
Corrosion represents a CHEMICAL change.
yes it is because a chemical change is way different than physical and a physical change is when it is still the same for example when you rip cut or crumble a pice of paper it is still the same !
it is a chemical change because it is no longer hydrochloric acid but a substance that has a different "ingredient" than it
physical changes can be not permanent like solid-liquid-vapour chemical changes are permanent if not reversible
