Question

___ occurs when molecules of the same substance are attracted to each other.

Cohesion
Adhesion
Surface tension

Answer 1

The answer is cohesion. Adhesion is when molecules of different substances (an example dew on a leaf) are attracted to each other. And surface tension is a force that creates sort of a thin layer on top of water, so that some small things are able to stand on water. That is how water striders are able to do what they were named after, stride on water.

Answer 2

Cohesion occurs when molecules of the same substance are attracted to each other.
