  3. Abstract:
  4. In this study by using a capacitive cell probe the temperature variation of the electrical properties of the water liquids is investigated. Variation of the reactance capacitance parameter of liquids with temperature in the range of 17-60°C is measured for the plain water and water mixtures. The temperature variations of the capacitance for the cool distilled and tap water samples are studied for the range of 17-29°C obtained. Present results indicate an averaged variation of 4.69 μF/°C for the distilled water and 3.24 μF/°C for tap water in warm up process to a near room temperature. The cooling behaviors for the warm mineral, tap and salt water liquids are also investigated in this study. Average variations of 0.54 μF/°C for the mineral water, 0.76 μF/°C for the tap water and 1.44 μF/ °C for the dilute salt water are obtained for the high temperature range. In comparing the results for different liquids, dilute salt water shows a factor of 2.6 increase in measured capacitance in comparison with the mineral water when temperature drops from 60.0 to 35.0°C. Hence the reported cell probe provides a relatively accurate method to determine the temperature dependence of reactive capacitance for the pure liquids and also liquids with a trace impurity. © 2009 Asian Network for Scientific Information
