Answer:
Physical and chemical changes are different because one deals with changes to ones shape or form, while chemical is changing one substance to another.
Step-by-step explanation:
A example of a physical change would be cutting a block of wood into a cube of would, its physical change changes from a block to a cube. A chemical change is changing the substance into another substance so for example, burning that cube of wood in a fire. The fire is burning the wood into ash meaning it's no longer wood but ash.
Hope this helps.
