Answer:
Capable of bonding to surfaces with the application of light pressure is a chemical reaction.
Step-by-step explanation:
Here, bonding occurs . Bonding results in destruction of old bond and formation of new bonds.Hence new substance with completely different properties is formed. These changes occur only in a chemical reaction .
In physical processes no new substance is formed (no bonding).So,no change in properties of a substance . ]
This process (capability of bonding to surfaces with the application of light pressure) results in chemical reaction.
This type of substances are called Pressure-sensitive Adhesives.(PSA)
