Answer Details
Thermoplastic materials soften and melt on heating. This means that they can be heated, molded into different shapes, and cooled to form a solid. Unlike thermosetting plastics, which harden irreversibly on heating and cannot be remolded, thermoplastics can be remolded multiple times without any change in their chemical structure. Therefore, the correct statement about thermoplastic materials is that they soften and melt on heating.
