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.
This latter case also applies to the case of a bubble surrounded by a liquid, such as the case of the alveoli of the lungs. Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. The spherical shape minimizes then necessary wall tension of the surface layer according to LaPlace's law.
