What is a physical and chemical change?

Answer 1

Answer:

Physical change is basically a change in where an object can easily return to its original state somehow as long as it’s possible but a chemical change is a change in which there is now simple way to change a substance back to original form. Basically (in simple words) chemical changes literally make something entirely new.

Explanation:

Physical changes come for example when you rip paper. You can easily fix it right up with some tape.

Chemical Changes is like rust on a bike or paper being burned. If that paper bein burned in flames you can’t put tape on the ashes and start writing on it like nuthin happend lol

Answer 2

Physical change: Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but can not usually be used to separate compounds into chemical elements or simpler compounds.


Chemical change: Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
