Technology and Operations Management. The scope of Technology and operation management has evolved over a period of time and has moved from development of products into design, management and improvement of operating system and processes.
Hydrogen bonding forms in liquid water as the hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule; generally, a proton shared by two lone electron pairs.
Surface Tension. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface.urface Tension of Water. The surface tension of water is 72 dynes/cm at 25Â°C. It would take a force of 72 dynes to break a surface film of water 1 cm long. The surface tension of water decreases significantly with temperature as shown in the graph.
