Part A Follow these steps, and record your findings in the table: Put 10 milliliters of distilled water into a test tube. Label it test tube 1, and place it in the test tube rack. Record the temperature of the water. Measure 1.00 gram of anhydrous copper(II) sulfate (white powder) into a weighing boat. Pour the anhydrous copper(II) sulfate into test tube 1. Measure the final temperature of the solution in test tube 1. Watch the thermometer for a couple of minutes, and record the highest temperature it reaches. Calculate and record the difference of the initial and final temperatures of water in the test tube.
