Which of these is an example of a physical change!

A baking a cake

B toasting bread

C grinding pepper

D lighting up a grill

Hey There,

Your answer is C) Grinding pepper

The pepper is still pepper, you are just changing the way it looks. Nothing has changed about it except its form. When baking a cake, toasting a bread or lighting up a grill, they are perform a chemical change. Not when grinding pepper.

Best Of Luck,
