yes it is a chemical change. the paint is oxidised by the atmospheric air to fade.
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.
It is a physical change.
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.
it is a chemical change, i was trying to do my chemistry homework and was searching for this too but ive found out it is a chemical change
It is a chemical change because it changes color when you mix 2 colors.
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 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)
