How are metal plastic and glass made?

Answer 1

Metals are typically extracted from their ores through mining and then processed by smelting and refining to remove impurities. Plastic is made from petrochemicals through a process called polymerization, where small molecules called monomers are chemically bonded to form long chains. Glass is produced by melting silica sand along with other raw materials like soda ash and limestone at high temperatures, then cooling and shaping it into desired forms. Each material undergoes distinct processes tailored to its chemical properties and intended applications.
