Because during painting the chemical structure of the dyes (the chemical formula of the molecule) remain generally unchanged.
Physical change of the paint, not the door.
Its a physical change
Painting a room involves a physical change rather than a chemical change. The process of painting a room typically involves applying a layer of paint, which dries and forms a new physical layer on the surface of the wall. Chemical changes involve the rearrangement of atoms and the formation of new substances with different chemical properties, which is not the case in painting a room.
this is a physical change
A physical change
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.
Physical change of the paint, not the door.
No, painting a door is a physical change, not a chemical change. The paint is simply adhering to the surface of the door through physical means such as drying and curing, rather than undergoing a chemical reaction to form new substances.

Paniting a wall is a physical change because it is the same wall but a different color
Chemical Changes the substance and physical really dont change it as much examples of chemical: burning wood, physical: painting it Physical is basically changing color, looks,
Spray painting a car involves a chemical change because the paint chemicals react to form a new substance that bonds to the surface of the car's body. This is different from a physical change, where the paint would simply be a new layer on top of the car without a chemical reaction occurring.
I guess it could be chemical, but really- it's a physical change
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.
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.
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.
