You are given two glasses A and B of equal volumes; glass A is tall, has a small base; glass B is short with a larger base. You fill them with water and leave them in the laboratory. After a few days, you examine them and find that the levels of water are lower in both glasses than when you left them. Then you decide to measure the remaining volumes.
Questions:
1/ What phenomenon caused that change?
2/ Do you expect to find equal remaining volumes in the two glasses? Justify your answer.
3/ Do you expect to find different remaining volumes in the two glasses? If yes, compare the remaining volumes VA and VB, and explain.
