This week we had to do an experiment on heat transfer. The four material I chose was aluminum foil, plastic wrap, coffee filter, and a cloth. My results showed that the cup of hot water with the coffee filter on it lost more heat than the rest. The other three materials were about the same. I chose these four materials from what I had in my home. The experiment I conducted heat was transfered by two methods conduction and convection. The third type of heat transfer radiation was not present in this experiment. Due to I conducted it in my kitchen with the lack of sun light.
If I were to repeat this experiment I would use the aluminum foil, plastic wrap, wax paper, and a ziplock bag. I would also heat my water in the microwave prior to covering the cups.
Why do you feel the coffee filter caused the greatest heat loss? If you changed the materials, do you think the plastic wrap and the ziploc bag would generate similar results or different results?
ReplyDeleteI feel that the coffee filter allowed the heat to escape due to it has holes to allow the water to drain. I feel that a ziplock would hold more heat than plastic wrap do to the ziplock is made with more materials than the plastic wrap. What do you think?
