Answer 1

To measure the volume of water in a graduated cylinder, follow these steps: place the cylinder on a flat surface and read the volume from the bottom of the curved surface (meniscus).

Step-by-step explanation:

To measure the volume of water in a graduated cylinder, the correct procedures are:

He should place the graduated cylinder on a flat surface to ensure stability and accurate readings.

He should take the reading from the bottom of the curve of the surface of the water (the meniscus).

These procedures help to ensure accurate measurements by minimizing human errors and taking into account the meniscus, which is the curved surface of the liquid in the graduated cylinder.
