Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems. Describe at least two real-world issues or examples that illustrate the findings of this experiment.

Answer 1

Experiment 1:

What happens to the water in the small tube as the water in the test tube absorbs heat?

Answer: As the water in the test tube absorbs heat the water in the small tube continues to rise

Why do you think a small tube was used to observe the expansion of water?

Answer: The small tube was used to observe the expansion of water to show a visible change that could also be measure with a ruler

Experiment 2:

Compare the circumference of the balloon before and after freezing. What is the percent increase in this measurement?

Answer: The circumference of the balloon increased after it was put in the freezer. The measurement increased by about 5%, it started at 39.5cm then increased to 41.5cm

According to the data, an increase in temperature caused the water molecules to expand because it gained energy which caused it to move more rapidly ultimately resulting in an increase of volume of water. In addition, when being froze water expands making it less dense than the water from which it freezes, causing the volume to also increase. The difficulty I faced in this experiment is pinpointing the exact change in the waters expansion. Two real world issues are when icebergs float as a result of water freezing resulting in expansion, another one is the warming of Earth due to the heat-trapping from greenhouse gases. This heat is absorbed by oceans and seas causing the temperature to rise and the water to expand.
