SCIE-6661S-1-Wk 4: Heat
This week I tested the transfer of heat through convection using a mug with no cover, a mug with aluminum foil, a mug with bubble wrap, and a mug with a cotton cloth. The experiment used convection because, the heat in the water turned into gas molecules that were trying to escape from the cup. The mug with nothing on it obviously got the coldest in the 30 minutes. The mug with the aluminum foil stayed the hottest. The aluminum foil acted as a insulator to keep the heat-gas molecules inside the mug.

Sara,
ReplyDeleteI looked at the results of your experiment and noticed that you are the only person on my list thus far who got the best results from aluminum foil. I also noticed that the bubble wrap was quite effective and really did not lose that much more heat than the aluminum foil cover. For myself and one other person, we found that the plastic material that we used worked better than the aluminum foil. It now leads me to wonder if the brand of aluminum foil played a role in its effectiveness or lack thereof in my experiment.
Sara,
ReplyDeleteI also found it interesting how well the aluminum foil did for you. I was expecting the aluminum foil insulate much better than it did for me. My best results were actually saran wrap and a dish towel. I, for some reason, did not chart temperatures (I don't know why I did not do that!) so it was nice to clearly see all of your results! Great blog!
