The task in the image involves determining the volume of liquid indicated on each graduated cylinder. Graduated cylinders are used to measure the volume of liquids, and the markings on the cylinder help in reading the volume accurately. Here's how to solve the problem step by step:
---
Step 1: Understand the markings on the graduated cylinders
- Each graduated cylinder has numbered markings that indicate specific volumes.
- The liquid level is read at the bottom of the meniscus (the curved surface of the liquid). If the meniscus is not visible, estimate the volume based on the closest marking.
---
Step 2: Analyze each graduated cylinder
####
Cylinder A:
- The markings range from 60 to 70.
- The meniscus appears to be just below the 70 mark.
- Estimate:
68 mL.
####
Cylinder B:
- The markings range from 30 to 35.
- The meniscus is clearly at the 30 mark.
- Estimate:
30 mL.
####
Cylinder C:
- The markings range from 75 to 85.
- The meniscus is slightly above the 80 mark.
- Estimate:
81 mL.
####
Cylinder D:
- The markings range from 40 to 50.
- The meniscus is just below the 40 mark.
- Estimate:
39 mL.
####
Cylinder E:
- The markings range from 60 to 70.
- The meniscus is clearly at the 60 mark.
- Estimate:
60 mL.
####
Cylinder F:
- The markings range from 30 to 35.
- The meniscus is clearly at the 30 mark.
- Estimate:
30 mL.
####
Cylinder G:
- The markings range from 70 to 80.
- The meniscus is clearly at the 70 mark.
- Estimate:
70 mL.

Step 3: Write down the answers
Based on the analysis, the volumes indicated on the graduated cylinders are:
-
A: 68 mL
-
B: 30 mL
-
C: 81 mL
-
D: 39 mL
-
E: 60 mL
-
F: 30 mL
-
G: 70 mL

Final Answer:
\[
\boxed{68, 30, 81, 39, 60, 30, 70}
\]

Explanation:
- Reading the volume from a graduated cylinder requires careful observation of the meniscus and interpolation between markings if necessary.
- Always ensure that the eye is level with the meniscus to avoid parallax errors.
- The estimates provided are based on the visible markings and the position of the meniscus in each cylinder.
