1.	How do we study the color of flame in Bunsen burner by regulating the flow of air ??????????
Answer» A Bunsen burner flame produces energy from burning gas. If the air hole is open the flame burns in plenty of oxygen. Combustion is complete and a\xa0blue flame\xa0is seen.\xa0Increasing the\xa0amount of fuel gas\xa0flow through the tube by opening the needle valve will increase the size of the\xa0flame. However, unless the airflow is adjusted as well, the\xa0flame\xa0temperature will decrease because an increased\xa0amount of gas\xa0is now mixed with the same\xa0amount\xa0of\xa0air, starving the\xa0flame\xa0of oxygen.
