1.	When exposed to ultraviolet radiatoin ( for example, from fluorescent lights), the white phosphorus slowly turns toA. black `P`B. yellow `P`C. Violet `P`D. red `P`
Answer» Correct Answer - 4 If white `P` is heated to about `250^(@)C` or a lower temperature in the presence of sunlight ,then red `P` is formed. This is a polymetic solid, which is much less reactive than white phosphorus. Violet `P` is formed by heating a solution red `P` in molten lead to `500^(@)C` ,and black `P`, is formed by heating white `P` under a pressure thousands of times atmosphere.
