The effect of applying the electric charge on the freezing of supercooled water was investigated using a pair of spherical electrodes, facing to each other in the test water. The reason for using a spherical end surface was to minimize unexpected high electrical density on the surface due to the existence of a singular point. After getting a uniform temperature, D. C. voltage was applied to the test section. Temperature, distance between two electrode sand the voltage applied were varied. It was found that supercooled water freeze in a few seconds after applying the electric charge. It was also found that the freezing is a statistical phenomenon. There are some tendencies, however, that the higher the value of D. C. voltage applied or the closer the distance between two electrodes are, the easier the water freeze. The electrical current was measured for every 0.05 seconds and it was found that the value increased while the voltage was being applied. The idea of a probability of freezing while a specific current flows for a time interval of Δt was introduced. The probability of freezing was calculated under two different conditions and the results were compared to each other to confirm the assumption. As a result, it was concluded that the probability depends only on the past record of current flow.
