Take a measuring cylinder and observe it carefully. Note down the following:

1. What is the maximum volume it can measure? Class 8

Answer:

The maximum volume that can be measured in a cylinder depends on the size of the cylinder.

2. How much is the volume difference indicated between the two bigger marks (for example, between 10 mL and 20 mL)? Class 8

Answer:

The volume difference between two bigger marks (say 10 mL and 20 mL) is 10 mL.

3. How many smaller divisions are there between the two bigger marks? Class 8

Answer:

There are 10 smaller divisions between the two bigger marks.

4. How much volume does one small division indicate? Class 8

Answer:

One small division indicates 0.1 mL.

The smallest volume that the measuring cylinder can read is 1 mL Class 8

5. Why are measuring cylinders always designed narrow and tall instead of wider and shorter like a beaker?

Answer:

Narrow and tall cylinders give a better measurement of volume.
