No. If one substance does not change into another, it is not a chemical change.
Evaporation is considered to be a physical change. The chemical nature and identity of the evaporated material is the SAME as that of the liquid.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
That's correct. In a chemical change, new substances are formed through rearrangement of atoms, but the identities of the original atoms remain the same. This is because atoms are not created or destroyed during chemical reactions, they simply rearrange into new combinations.
The chemical nature/identity of the substance stays the same when a physical change takes place.
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
The statement is false: A chemical change of a substance is defined as a change in which the substance is not the same substance after the change as it was before.
Yes, during a chemical change, the chemical composition of the substance is altered, which means new substances are formed with different properties. However, the identity of the original atoms remains the same, as they are rearranged to form new compounds.
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
No, in a chemical change new substances are formed with different chemical properties compared to the original substances.
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.
