The molecules in liquid water are attracted to one another but are able to slide past each other. If you look closely, you can see some molecules where the hydrogen atoms of one molecule are “bonded” ...

Students investigate the polarity of the water molecule and design tests to compare water to less polar liquids for evaporation rate, surface tension, and ability to dissolve certain substances.

The water molecules were fixed atop a salt film under ultra-high-vacuum conditions (10 –11 Torr) and extreme cryogenic temperatures (between -268.75°C and -257.15°C) to prevent evaporation.
