Step-by-step explanation:
In order for pure substances to combine into new materials, a chemical change must occur. This type of change involves the rearrangement and/or reorganization of the atoms in the substances, resulting in the formation of new substances with different chemical and physical properties.
Some examples of synthetic materials that can be produced through chemical changes include plastics, ceramics, and various types of composites. Plastics are synthetic polymers that can be molded into a variety of shapes and are known for their durability and versatility. Ceramics are inorganic, non-metallic materials that are made by heating and then cooling clay and other materials. Composites, on the other hand, are materials made from two or more different substances that are combined to create a material with improved properties, such as increased strength or durability.
