In classical science physics was essentially the science dealing with motion: an example of classical physical process is the flowing of water in a tube or the motion of the football ball.
In the same context, chemistry deals with transformation of one molecule in the other (chemical reactions), so that a typical chemical phenomenon is the salt formation by reaction of Hydrochloric Acid with Sodium Hydroxil in water solution that writes
HCl + NaOH (water solution) -> NaCl + H2O (water solution)
With the introduction of quantum theory of atoms and subatomic structures, physics started to describe with physical theories chemical reactions. For example the quantum theory of molecular orbital (without any doubt a physical theory) is the base for the modern explanation of chemical bonds, that are the links maintaining different molecules together.
Moreover, nuclear physics has started to describe much more drastic transformations like nuclear reactions transforming atoms in other atoms.
Thus at today it would be more correct to say that chemistry is a particularly extended branch of physics.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
It is both physical and chemical. Evaporation of water is a physical process, and reduction of water from clothing is also a chemical process.
No, a decaying compost pile is not an example of a physical change. The process of composting results in a different physical appearance or state -- which is physical change -- but it is not reversible and necessitates a change in structure -- which is chemical change.
It is a physical change because the change is reversible.
Precipitation in weather terms (rain, snow, etc.) is a physical process. Precipitation in chemical terms (e.g. lead iodide falling out of solution) is a chemical change.
Melting is a physical process.
Evaporation is an example of a physical change, as the chemical composition of the substance is not altered in any way.
Making glue is a chemical process.
Turning off lights when not in use, using public transportation or carpooling, and unplugging electronic devices when not in use are all examples of energy conservation. These actions help reduce energy usage and lessen the overall demand for energy production.
Melting of ice with salt is example of physical change as there is no chemical reaction involved .
An example of a non-physical weathering process is chemical weathering, where rocks are broken down by chemical reactions rather than physical forces like temperature changes or abrasion.
Melting of ice into water is an example of a physical change. This is because the ice changes from a solid state to a liquid state without any alteration in its chemical composition.
No, it is a chemical process.
