The rate of migration of ions is inversely proportional to resistance.

Hence, the greater the movement of air, the greater is the evaporation. The current is mainly conducted between the electrodes by buffer ions. This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Air pressure also affects evaporation. The distance traveled by the ions is directly proportional to the current and the time. Thus, at a low ionic strength the proportion of current carried by the buffer decreases and those carried by the sample increases. Based on how much sunlight hits Earth versus how much is reflected, Earth’s average temperature should be well below freezing. Limiting Factors. Proportion of current carried by buffer increases and the one carried by sample decreases with the ionic strength of the buffer. For purposes of this example, the average flow is used as the desired flow rate out of the equalization basin. As the climate heats up, rainfall patterns changes, evaporation increases, glaciers melt and sea levels rise. Resistance of an electrophoresis unit depends on its size, gel thickness, amount of buffer, buffer conductivity, and temperature. Several procedures have been developed to assess the evaporation rate from these parameters.
