Physical, Because The Color Changes.. Not The Chemical Property Of The Paper.. :)
Chemical change.
Posters fading is a chemical change. The chemical properties of the poster originally reflected a lot of light, but when they fade (usually due to overextended sunlight exposure), the chemical properties of the poster change to reflect less light.
No. It is a physical change.
It is a chemical change because chemical reactions are involved - photochemical degradation of dyes.
It is a physical change because the sun's rays create a physical differential not chemical relates to chemical change ie: the ice tea crystals dissolve in the water. --------- Chemical change, because fading in this case is the result of a photochemical reaction.
Chemical broooooooooooooooo niga

No. It is a physical change.
Melting in a warm atmosphere is a physical change; but the oxydation in air or the thermal degradation of butter are chemical changes.

Decomposition is a chemical change, therefore, when decomposition results from exposure to ultraviolet light, that reflects a chemical property.

Chemical I think
physical as the chemical structure does not change.
