Question

Thermoplastic are:

Options

• Linear polymer.

• Soften or melt on heating.

• Molten polymer can be moulded in desired shape.

• Linear polymers, soften or melts on heating, and molten polymer can be moulded in desired shape.

Answer 1

Linear polymers, soften or melts on heating, and molten polymer can be moulded in desired shape.

Explanation:

Thermoplastics are generally linear polymers. They soften or melt on heating and become hard again on cooling.
Because of this property, the molten plastic can be moulded into desired shapes repeatedly.
