Answer 1

Explanation:

Thermoplastics can be softened by heat but thermosetting plastics cannot be softened by heat. This is due to the difference in their structure. ... Due to this, on heating, the individual polymer chains can slide over one another and thermoplastic material becomes soft and ultimately melts.

Answer 2

Answer:

Thermoplastics become soft on heating because the arrangement of monomers in them are in straight line chain,whereas the arrangement of monomers in the thermosetting plastics is in a crossed link chain therefore the thermosetting plastics do not melt on heating.
