non- thermal effect I. INTRODUCTION Application of microwave irradiation for chemical processes, such as emulsification and polymerization, has been reported [1,2]. Surfactant free emulsion can be produced with the help of microwave irradiation. Surface tension is an important property for the industri...
a== H2O == Water is H2O, 2 molecules of hydrogen and 1 molecule of oxygen. Water is slightly polar (has an electric charge). Surface tension and capillary action are the properties that result from polar water molecules. Surface tension is the property of water molecules clinging to each ...

The surface tension-temperature relationship for water is smooth and linear when account is taken of the expansion of the surface with temperature. This plot permits the calculation of thermodynamic properties for 1 square centimeter of surface. Molar surface quantities are derived by assuming a hexago...

LAB: SURFACE TENSION Introduction: Due to hydrogen bonding, water molecules tend to stick together. Surface tension refers to water's ability to "stick to itself". Surface tension can be measured and observed by dropping water (drop by drop) onto a penny. The number of water drops that can...
○Surface tension is not strong enough to retain drops of water in rocks with large pores but it strong enough to hold on to thin films of water in rocks with small pores. ○Water in rocks is held in place by large pores and drains away from small size pores through surface tension. ...
