What are the physical propertis of plastic

 hardness, density, tensile strength, resistance to heat and glass transition temperature,

Explanation:

Hi, plastic materials consist of long chain molecules (polymers). Available in many colors and in transparent form, plastics can be rubbery or rigid. Plastic shapes include sheet, rod, hex, pipe, cubes, balls, and tubes.

The physical properties of plastica are:  hardness, density, tensile strength, resistance to heat, glass transition temperature, ductility and chemical resistance, among others.
