Increased temperature of a solution increases its solubility, allowing for a greater level of dissolution of the solute. A greater level of dissolution will result in a change in the density of the solution. When a localized area of the solution is of a different temperature, this will affect the localized density. Density is one of the factors affecting rate of sinking and the difference in temperature will lead to a change in the rate of sinking. Thus, when an object is at different temperatures, it will transfer heat to or from the solution in different manners and the rate of sinking will be different. This study tested whether sinking rate in a solution with excess solute could be used to judge the temperature of an object and the effect was confirmed with impure Graphite blocks in a Potassium Iodide solution.
