A glass beaker is half filled with water and an empty glass tumbler is inverted and lowered inside the glass beaker. State your observations on tilting the tumbler below the level of the water in the glass beaker. Give a reason for your answer.
Answer
An empty glass tumbler when lowered inside a glass beaker half-filled with water and tilted, the air inside the tumbler is displaced and bubbles of air are seen coming out. The reason is that the air is pushed out by water on tilting the tumbler inside the beaker of water since air or gases occupy space.
