The Law of Motion is once again demonstrated.
The absorption of water is not a chemical reaction.
There is no chemical or physical reaction in this test.
During a physical reaction, the arrangement of atoms and molecules changes, but no new substances are formed. This means that the chemical composition remains the same before and after the reaction. Examples of physical reactions include changes in state (solid to liquid, liquid to gas) or changes in shape.
the potential energy of the molecules changes during a reaction.
It is a physical process, not a chemical reaction.
Neutrons released during a fission reaction trigger other fission reactions.
During boiling the chemical composition is not changed.
A physical reaction, or change, is one that can be observed without changing the chemical composition of the substance. Boiling is a physical change because the substance that is boiling does not change its chemical composition. For example, water is still H2O whether it is boiling or not boiling.
The potential energy of the molecules change during a reaction.

Chemical equations are used to show what happens during a chemical reaction. They demonstrate the reactants that are used, the products that are formed, and the balanced relationship between them. Symbols and formulas represent the different elements and compounds involved in the reaction.
Its physical shape is unaltered, ready to repeat its functional action.
