yes there is no chemicals changing and it is just looking diffrent so it is phyisical
Evaporation is a physical change.
Fireworks that are set off are a chemical change.
Physical change...just think of it as if you were getting your hair "chopped" off. You only temporarily change your appearance and eventually it grows back and so will the tree.
yes, shooting off fireworks is a chemical change because decomposition reactions occur and the nature of the initial chemicals is changed.
First off, its spelled "breaking". No, Its a physical change, because the pencil hasn't changed its chemical components, all you did was ruin a pencil. :)
Breaking off a branch of a tree is a physical change.

Sanding rust off of a metal is a physical change. You are changing the rust's location, but not its chemical structure.
PHYSICAL
Properties: -Ability to burn. -Bubbling. -Color (can be physical as well). -Corrosion. -Explosiveness. -Foaming. -Odor. -Rotting. -Rusting. Changes: -Absorbs heat to become cooler. -Becomes magnetized. -Blowing up (explosion). -Burning. -Change in odor. -Color change (can be physical as well). -Gives off heat. -Glowing. -Production of gas bubbles. -Formation of a precipitate.

I would think it to be a Physical Change. Not chemical.

Sharpening a pencil is a physical change, because there is no change to the chemical makeup of the pencil when sharpening it. It is simply chunks of wood being sliced off to reveal more of the lead.It is a physical change.
