Heat and Dissolution

• Conduct an experiment into how heat affects the dissolving of salt, sugar or other solubles in water. Half-fill a measuring cup with tap water at 40 degrees Ft. Add a tablespoon of your soluble to the mix and start a timer before stirring the contents of the cup with a spoon in a uniform, even fashion; you must be able to repeat this stirring action at the same speed and profile later. Observe the contents of the cup until the material has dissolved completely. Write down the time. Repeat this test for different temperatures of water, again half-filling the cup, using 1 tbsp. of your soluble and stirring using the same spoon, speed and profile. Compare your results for different temperatures.
