1.	Vidya went to her hradfather Rajam's house to spend her summer vacation. Rajaram has coconut fields near him house. It the evening she went to the coconut field along with her grandfather. There the workers offerd her coconut water. Her grandfather told worked to provide a straw to facilitate drinking the coconut water comfortably. Can you explain the principle behind using straw for above purpose ?
Answer» Solution :When we SUCK ONE end of a striw dipped into the coconut water some AIR from inside the straw is drawn out. A partical vacuum is carated within the straw as a reasult coconut water is pushed up by the atmospheric pressure to fill up the vacuum and REACHES the persons mouth. Hence we can drink the coconut water.
