A physical change does not change the identity of matter.
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
Melting ice to get water, or boiling water to get steam, doesn't change the identity of H2O.
It does change its physical look but it does not change chemically.
when matter goes through a physical change, that state of the matter changes. so if i took liquid water and froze it into ice... that would be a physical change because it is still the same compound in a different form
cooking an apple is causing a physical change because in a physical change, the IDENTITY of the substance never changes. (identity=atomic makeup. in a chemical change, the IDENTITY does change, due to a chemical reaction. because there is no change in the identity of the apple, baking it is a physical change
a physical change
A change of phase doesn't change the chemical composition of a substance.
No, the chemical nature of the reactants is changed.
the volume or mass of the matter. it can change states such as solid liquid or gas, which would be deemed to be the same chemical identity, but a different state of matter
because they change the identity of the matter
Physical property
This is called a physical change. If a new compound is formed, its called a chemical change.
Changes of the matter that do not change the composition of the substance.
Chemical Change
Any change in matter that is does not require the identity of the matter to change is physical. Things like sizzling, popping, effervescence, etc. are physical change. Something to keep in mind though: Anything that burns is undergoing chemical change, no matter what. Any combustion is chemical.
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.
