Discover the amazing properties of water's surface tension as you make metal paper clips float on water. You'll learn about the forces that hold water molecules together and how insects like water ...

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.

Discover how surface tension keeps water molecules together and how soap can break this force. Watch as pepper flees from soap in water, demonstrating molecular interactions in an exciting way. Watch ...

some 20 dynes per cm. less than the surface tension of water. Bile, and agar and gelatin in nonsolidifying concentration fall within the same range. The effect of various inorganic and organic ...

The terminology for herbicidal additives is confusing. It is often assumed that any material that lowers the surface tension of water in the spray mixture or increases the wetability of the spray ...
