How could latent heat be explained from the graph drawn to study effect of heat on ice?
Answers
Surface Tension
Next to mercury, water has the highest surface tension of all commonly occurring liquids. Surface tension is a manifestation of the presence of the hydrogen bond. Those molecules of water that are at the surface are strongly attracted to the molecules of water below them by their hydrogen bonds. If the diameter of the container is decreased, the combination of cohesion, which holds the water molecules together, and the adhesive attraction between the water molecules and the glass container will pull the column of water to great heights. This phenomenon is known as capillarity. This is, in part, what allows plants to stand up--when too much water is lost by evapo-transpiration, they wilt.
