Physical Change

What is a Physical Change?

I have learned the following things
from this video. A physical change
is when you change its size and
shape but not what it is. Like for
example, when you get a piece of
paper and make it into a plane
you just changed its shape but
you didn’t change what it is.
Even if you chop some vegetables
they are still vegetables but you
just changed its size and shape.
Such as paper scrunching, tearing
paper, making different things out
of paper are not chemical changes,
but physical change.
