To solve this problem, we need to read the volume of liquid in each graduated cylinder. Here’s how we do it step by step:
1.
Identify the scale: Each cylinder has markings that represent units of volume. The numbers on the side tell us the value of each major line.
2.
Find the meniscus: The surface of the liquid forms a curve called the meniscus. We always read the volume at the bottom of this curve.
3.
Determine the unit: Look at the numbers and see what they increase by. For example, if the numbers go 0, 10, 20, etc., then each major line is 10 units. If there are smaller lines between them, count how many there are to find the value of each small line.
4.
Read the volume: Find where the bottom of the meniscus aligns with the markings. Count the lines from the nearest labeled number to get the exact volume.
Let’s apply this to each cylinder:
-
(a): The meniscus is at the 50 mark. So, the volume is 50 mL.
-
(b): The meniscus is at the 60 mark. So, the volume is 60 mL.
-
(c): The meniscus is at the 70 mark. So, the volume is 70 mL.
-
(d): The meniscus is at the 40 mark. So, the volume is 40 mL.
-
(e): The meniscus is at the 50 mark. So, the volume is 50 mL.
-
(f): The meniscus is at the 60 mark. So, the volume is 60 mL.
-
(g): The meniscus is at the 50 mark. So, the volume is 50 mL.
-
(h): The meniscus is at the 50 mark. So, the volume is 50 mL.
-
(i): The meniscus is at the 50 mark. So, the volume is 50 mL.
Final Answer:
(a) 50 mL, (b) 60 mL, (c) 70 mL, (d) 40 mL, (e) 50 mL, (f) 60 mL, (g) 50 mL, (h) 50 mL, (i) 50 mL
