Is a new substance is produced a chemical or a physical change?
That's a chemical change because the structure of the atoms are changing. Chemical features can only be viewed through chemical change, by the way.
What happens when a clear substnace undergoes a chemical change?
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.
When a physical change in a sample occurs which does not change?
Substance in the material Remain the same
What is the difference between physical change and chenical change?
In a physical change, the chemical composition of the substance undergoing the change remains the same. In a chemical change, atoms are rearranged, forming new products with their own unique chemical compositions and properties, different from the original substance or substances.
What are the differences between a chemical and physical change?
A physical change doesn't change the molecular properties of a substance. Some examples of physical changes include tearing paper, or the evaporation of water. A chemical change does change the molecular properties of a substance. For example, if you burn wood you get leftover carbon, and CO2 is also released; no longer does the wood have the same molecular properties or structure.
What are the signs of physical change and chemical change?
Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
What are characteristics that describe the ability of a substance to form a new substance?
Chemical change or chemical reaction describes how a substance can form a new substance.
Are the atoms in a substance the same if the substance changes states?
On heating there will be a change in the physical state not chemical composition. So the number of atoms will be the same even after change in state.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
When a new substance is produced is it a chemical or physical change?

Is human growth a physical or chemical change?
Neither - a human is not a physical or chemical change. A human is a type of living multicellular organism.A physical change is a process where the actual molecules and atoms of a substance do not change, but appearance will change.A chemical change is a process where the actual molecules and atoms of a substance change, usually along with the appearance.
When a substance undergoes a physical change what does not a change?
The chemical make up of a substance does not change. It must remain the same combination of atoms or molecules to be considered only a physical change.
When a physical change in a sample occurs which does not change?
Substance in the material Remain the same
