Name the phenomenon that is being demonstrated in this experiment. how is it that the water in the glass does not spill. |

Answer» CohesionExplanation:This happens because the FORCE of gravity naturally pulls down on the water.This cohesive force is the origin of surface tension.) In the upside-down glass, it helps prevent the FIRST water drop from separating from the rest of the water volume. As a result, the pressure difference required to KEEP the water in the glass is less than WOULD be NEEDED if there were no cohesive force. |
