Paneling a room, or in other words applying wood panels to the walls of a room in order to modify the look and feel of the room, would be a physical change and not a chemical change because you are changing the physical properties of the room and not the chemical composition of the room.
Painting a room would be a physical change.

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

No.

it is a physical change.
Physical - because you're changing the appearance - not the composition of the wall.

I guess it could be chemical, but really- it's 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.
No. It's an observed fact, not a "change" of any sort, chemical or otherwise.
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
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,
