Question
A round bottom flask containing coloured water, filtered with a stopper and a narrow glass tube is shown in the following diagram. What will happen to the water level X marked in the tube when it is placed in a hot water bath? Give a reason for your answer.
Solution
The level will rise above X when the flask is kept in a hot water bath because the water in the flask will heat up and expand in volume thus raising the level of water in the tube above X
