Question
Chapter 12, Problem 12.5QP
Interpretation Introduction
Interpretation:
The reason for glass filled with water slightly above the rim but overflow of water not caused has to be explained.
Concept Introduction:
Surface tension refers to the attractive forces between the liquid molecules in the bulk of the liquid and those molecules in the surface of the liquid. Greater the strength of the intermolecular force or cohesive force greater will be the surface tension.
