Question

cohesion between molecules at the surface of a liquid is called surface tension. water molecules below waters surface form hydrogen bonds with molecules all around them. but water molecules at the surface form hydrogen bonds with only the molecules next to and below them. so, molecules at the surface experience a strong downward pull from the molecules below. this causes surface molecules to pull together, forming a barrier on waters surface that is resistant to breaking. surface tension allows some insects, like water striders, to walk on the surface of a pond. surface tension is also responsible for the spherical shape of a water drop. select the true statements. hydrogen bonds between waters surface and a water strider allow it to walk on water. surface tension only forms on large bodies of water, such as lakes and ponds. water molecules on the surface are pulled downward by the molecules below. surface tension only forms on small amounts of water, such as raindrops and dewdrops.

Explanation:

1. Water striders walk on water due to surface - tension, not hydrogen bonds between water's surface and the water strider.
2. Surface tension forms on any body of water, large or small, as it is a property related to the cohesive forces between water molecules at the surface.
3. Water molecules on the surface are indeed pulled downward by the molecules below, which is a cause of surface tension.
4. Surface tension is not limited to small amounts of water; it exists on all water surfaces regardless of size.

Answer:

Water molecules on the surface are pulled downward by the molecules below.
