Homework Answers
1. As we increase the number of transfers, the volume of the water in the graduated cylinder decreases. As we go transferring, some molecules do not get transferred from one cylinder to another. As a result after many transfers we find decrease in the volume.
2. Please mention what is VB and VA so that their quotient can be found out
