Final answer:
To find the volume of a test tube using a graduated cylinder, pour the liquid into the cylinder and read the volume at the bottom of the meniscus. Estimate the volume between the marked lines and record the value.
Explanation:
To find the volume of a test tube with 38.8 mL using a 10 mL graduated cylinder, you would need to measure the volume in multiple steps. First, pour the 38.8 mL of liquid into the graduated cylinder.
Next, you would read the volume by looking at the bottom of the meniscus (the curved surface of the liquid). In the graduated cylinder, there are smaller lines between the labeled markings. By mentally subdividing the distance between these lines, you can estimate the volume more accurately.
Finally, record the volume by estimating the value between the marked lines. In this case, since the graduated cylinder can only measure up to 10 mL, you would report the volume as 10 mL, indicating that it is greater than 10 mL without an exact measurement.
