Explain with help of an activity that synthetic fibres melt on heating. |

Answer» A SYNTHETIC fibre is also a chain or small units joined together. Each small UNIT is actually a chemical substance. Many such small units combine to form a large single unit called a POLYMER.The word ‘polymer’ comes from two Greek words; poly meaning many and mere meaning part/unit. So, a polymer is made of many repeating units.Polymers OCCUR in nature also. COTTON, for example, is a polymer called cellulose. Cellulose is made up of a large number of glucose units. |
