Process that does not change the identity of a substance?
A physical process does not change the chemical identity of a substance. Examples include changing the state of matter (like melting or freezing), dissolving, or distillation.
What is the term for a process that does not change the identity of a substance?
The term for a process that does not change the identity of a substance is a physical change. This type of change alters the appearance or state of a substance without changing its chemical composition.
During physical changes what does matter always retain?
During physical changes, matter always retains its chemical composition, which means the atoms and molecules in the substance remain the same before and after the change. This is because physical changes involve rearranging molecules or changing the state of matter without altering the fundamental identity of the substance.
Physical properties are altered but the substance remains the same kind of matter?
Physical properties are characteristics that can be observed or measured without changing the composition of the substance. When physical properties are altered, such as when a substance changes state (solid to liquid), the basic chemical composition remains the same, indicating that it is still the same kind of matter.
When the substance undergoes a chemical change its identity deos not change?
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.
