9. In many cases, all (or most) of the dialysis tubings gain weight during the experiment, which is an experimental artifact related to the use of clamps. Can you think of a reason why this may occur and what could be done to prevent this? Hint: Consider how weights are determined before and after their placement into the solution.

Testing the Effectiveness of Air and Blubber as Thermal Insulators
As this is a virtual exercise, the following experiment has been performed for you. Completed
steps appear in italics and do not require any action on your part. However, you must read each
of the steps carefully so that you understand the procedure. Data and supplementary
materials/videos will be supplied by your instructor. Complete all required steps and answer
the questions that follow.
1. Obtain 3 ice-filled bins which will serve as experimental chambers.
2. Next, obtain storage bags containing the insulating material (vegetable shortening/fat,
and air) and the control storage bag (containing no material), and 3 Celsius
thermometers.

3. Place the control bag in the first chamber on top of the ice in the bin. Rest a
thermometer on top of the storage bag with the numbers facing up, and record the time
and temperature immediately in Table 5.
4. Place the bag containing air packets over the ice in the second chamber. Rest a
thermometer on top of the storage bag with the numbers facing up, and record the time
and temperature immediately in Table 5.
5. Place the bag representing blubber (vegetable shortening/fat) over the ice in the last
chamber. Rest a thermometer on top of the storage bag, with the numbers facing up
and record the time and temperature immediately in Table 5.
6. Hypothesize the effectiveness of each 'insulator' relative to the other(s), and rank
each from best to worst in the spaces provided below.
None (control):
Air:
Fat:
7. Continue to record the temperature for each bin every 5 minutes for 15 minutes. Be sure
not to touch the thermometer when observing its temperature. Use data provided by
your instructor.

Expert Solution
Step 1
This is a fact that during this experiment the dialysis bags or dialysis tubings gain weight because of the sucrose solution present in it.
