Physical change of the paint, not the door.
Because during painting the chemical structure of the dyes (the chemical formula of the molecule) remain generally unchanged.
it is a physical change
Painting is a physical change.

Answer the door!The door was locked. A home webpage is the door to that website. I locked every door and window.
Yes because work is using energy to move something. Anytime we push-pull, work (energy) is used.
the fulcrum(pivot) is the screw in the door.

Painting a door is a physical change because the appearance of the door was changed. It is not a chemical change because it didn't chance its composition. After painting the door it still remained a door, just a different color.
No.
no. in order for a chemical change to take place the chemical make up of the paint would need to change, such as a color change. when you peel paint off a door you arent changing its chemical state.
Yeah it's a physical change because you're not changing the chemical composition of the door. You're simply changing the state that it's in. If you were to try to reverse the process (by opening the door), you could and afte you reversed it, you would still have the same door. However, an example of a chemical change is like baking cookies. If you were totry and reverse the process, you wouldn't be able to. You can't take the eggs out of cookies once you've made them, they're pretty much stuck in that state.
The formation of rust is a chemical change because the steel (iron) in the door has reacted with oxygen in the air to form a new substance called rust, which has properties different from the iron and the oxygen that reacted.
The door was cut into the painting in 1652. At the time, the painting was unrecognizable, and the door has since been bricked up. Exactly who cut the door is not known.
Well. Lots Of People Know About This So It No. Don't make a secret door behind the painting because people who play minecraft know about this and may try to steal the staff you hide in the secret door behind a painting.
The oxidation of the iron in a car door into iron oxide is a chemical change. The reaction equation is 4 Fe + 3 O2 = 2 Fe2O3
We removed the hinge in the door jam before painting and now we can't line up the door correctly. The build-up of paint is not an issue.
The fridge reacts with oxygen in the air, therefore creating rust. An example of a chemical property is ability to react with oxygen.
get a paintingmake two blocks (stacking)put a door next to the stacked blocks (remember to keep the door closed)keep putting the painting until you get a four-blocked paintinggo to the other side of the dooropen the doorgo to the other side of the door(as you can see, you can walk through the painting) (people wont know the magic painting)
