Question

Explain why liquids in a test tube are attracted to the surface of the test tube?

Answer 1

Answer:

When you put water in a beaker or test tube, you see a curved surface. With most liquids, the attractive force between the liquid and the container is greater than the attraction between the individual liquid molecules. So the liquid "sticks" to the side of the container. ... A few liquids have a "backwards" meniscus.

hope it helps.....mark as brainliest if it helps u:)✌
