The official definition for the phrase physical weathering is " a term used in science that refers to the geological process of rocks breaking apart without changing their chemical composition.
physical, just the aligning of magnetic domains what were previously random in orientation.
The freezing of water is an example of phase change.
Compression of nitrogen or any gas does not alter the chemical property...only changes involve in physical properties... On compression the gas molecules are come into more close..so it is pressurized..not change its chemical property...and whenever chances is come it s expand ..
Yes, lightening is a chemical process. Just add bleach to your wash, and see your clothes lighten. If you possibly meant, "lightning", no -- it's a physical process, but it does generate chemical changes.
The chemical composition is not changed during a physical process.
No, condensing is a physical change, not a chemical change. It is the process of changing a substance from a gas state to a liquid state by removing heat energy.
This process involve chemical reactions but also physical changes.

Evaporation is an example of a physical change, as the chemical composition of the substance is not altered in any way.
TRUE!
Growing vegetables can be a chemical process. However it is most likely that growing vegetables is a physical process because the chemical composition does not usually change.
The process is called mechanical weathering. It involves the breakdown of rocks into smaller fragments through physical processes such as frost wedging, root action, and abrasion, without altering the chemical composition of the rock.
physical reaction, because there is no change in its chemical composition.
Dissolving salt in water and making ice cubes
because the chemical composition of the nail is changed, forming a new substance (the rust)
It is a physical process because the chemical composition remain unchanged.
