Chemical change
Physical
yes it is
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.
This depends on the type of paint. In oil paint there is a physical change as volatile substances evaporate - and a chemical change as the paint hardens. In water-based paint (latex based) the paint loses water and so that part is a physical change - from wet to dry. But it also polymerizes (hardening, irreversible) which is chemical. Only washable paint is physically drying by evaporation (reversible, otherwise it wouldn't be 'washable').
The color is a physical property.The paint is a chemical product.

Physical change of the paint, not the door.
yes it is
Both, strangely enough. Applying the paint to the car is a physical change. The paint is a polyurethane compound. When you get it, it's in at least two containers - the paint, and a hardener. Stir them together and they undergo a chemical change.
yes ............... paint bubbling is a chemical reaction. when anything bubbles you know there is a chemical reaction.
No, because the paint simply sits on the surface of the wood, and there is no change to the molecules in the wood. Therefor, it is a physical change, until its dries then its a chemical change.
yea its a physical change cause i said so

The mixing of red paint and yellow paint should yield orange so your pigments must be undergoing a chemical change (the molecule is breaking down and reforming)

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. :)
