Well theres one last question left on my homework. I can't think of any reasoning for a correct answer. I just can't see why 1 cylinder is better then the other.
Heres the question
2. Of the following graduated cylinders - 100mL, 25mL, or 10mL - Which would you use to most accurately measure 8mL of a liquid? Explain you answer.
If you guys and girls can give me some help, I can go to bed and be fresh for school and the football game after. I need to have a big game tomorrow.

Smaller volumed cylinders have more space between the marks, (or finer graduations) so it is easier to get an accurate measurement in the smallest cylinder that holds the sample.

OK! Now you can go to bed and unwind because of this answer:
The graduated cylinder which has the volume of 10mL would be the most accurate of the three. If you will notice, the lines of the other graduated cylinders are many. Because of this, it will be hard for you to locate the correct number you are finding...
ILLUSTRATION:
1) 1 ' ' ' ' ' ' ' ' '10 ' ' ' ' ' ' ' ' ' 20 - hard to locate the number 8
2) 1 ' ' ' ' 5 ' ' ' '10 ' ' ' '15 - much accurate than #1
3) 1 ' 3 ' 4 ' 5 ' 6 ' 7 ' 8 ' 9 ' 10 - most accurate

10mL. The increments are the smallest. On the larger ones the increments would be about 3-5 apart as opposed to 1-2 on the smaller one.
