Under experimental investigation is the influence of various external factors such as electromagnetic waves, saturation by air and ozone, electrical discharge on the surface tension of water. Experiments have shown that the irradiation of water by electromagnetic waves causes reduction of the surface tension, the effect being dependent on the time of irradiation. The influence of electromagnetic waves in a centimeter range reduces the water surface tension from 67.91·10-3 N/m to 62.61·10-3 N/m during 10 minutes and to 57.96·10-3 N/m during 30 minutes of radiation. The numerical value of the activity factor of the water under study becomes 8.46% and 17.16% for 10 minutes and 30 minutes of irradiation, respectively.
Keywords: water, surface tension, irradiation, activity of water.
