Thes are the substances with pharmacodynamic effects.
These are substances with phaemacodynamic efects as drugs.
These are substances with phaemacodynamic efects as drugs.
These substances are called pharmaceuticals drugs.
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).

Physical because its not changing the chemical properties just the physical appearance
Decomposition is a chemical change, therefore, when decomposition results from exposure to ultraviolet light, that reflects a chemical property.
Melting in a warm atmosphere is a physical change; but the oxydation in air or the thermal degradation of butter are chemical changes.
Physical, Because The Color Changes.. Not The Chemical Property Of The Paper.. :)

It is a chemical change because chemical reactions are involved - photochemical degradation of dyes.
