I REALLY NEED HELP! so ive been taking this online class and I cant afford to but these things, so I would appreciate help from anyone. All have right now makes the water warmer and the water is 20 degrees celsius. 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.

Initial temperature (°C):
Final temperature (°C):
Temperature change (°C)

So I don't think this would change much but the second question is

Put 10 milliliters of distilled water into a second test tube. Label it test tube 2, and place it in the rack.
Record the temperature of the water.
Measure 2.00 grams of anhydrous copper(II) sulfate (white powder) into a weighing boat.
Pour the anhydrous copper(II) sulfate into test tube 2.
Measure the final temperature of the solution in test tube 2. Watch the thermometer for a couple minutes, and record the highest temperature it reaches.
Calculate the change in temperature.

Initial temperature (°C):
Final temperature (°C):
Temperature change (°C)
