Two 1 -litre flask A and B are connected to each other by a valve whic – InterviewSolution

1.	Two 1 -litre flask A and B are connected to each other by a valve which is closed. Flask A has benzene in equilibrium with its vapours at 30^(@)C. The flask B, is evacuated, and the valve is opened. Which of the following is true. I f temperature is kept constant.'
Answer» Some of the benzene molecules WOULD MOVE to flask B from flask A. Vapour pressure will be half the initial value. The vapour pressure REMAINS unchanged Some more of the LIQUID benzene in flask A would evaporate. Solution :There is no CHANGE in vapour pressure.
