endothermic dissolution process
An example of an endothermic dissolution is dissolving potassium iodide in water.

Added: Here is a table of Enthalpy of Solution for various compounds. Since this is the enthalpy of solution, some compounds will release energy when dissolve when the table indicates it would require energy to dissolve, and vice versa. If the number is negative, it is likely to be exothermic, and positive number are likely to be endothermic.
