Slow variations of the electroconductivity of distilled water

详细

The conductivity of distilled water with a slow change in temperature has been measured experimentally and studied. Periodic variations in the electrical conductivity of water have been found, which are observed at the rate of temperature change dT/dt < 0.1 K/h. The periods were longer than 24 h; the amplitudes of the variation ranged from +2.7% to–2.3%. The possible causes of the observed phenomena are discussed.
