Analyze 1. I could tell that the heat was being conducted along the metal bars, because the wax which was placed on the bars was melting in a relatively short period of time. 2. a- no, we found that the metals had varying rates of conduction depending on the metal type. b-copper,zinc,aluminum,tin,lead,carbon Conclude and Apply 1.Since metal is a conductor, putting heat on the metal caused the heat to spread along the length of the bar, melting the wax. 2.I would use carbon to stir a hot mixture because it seemed to conduct heat the slowest. Pg 461 20 a- the albedo of a city would be highter than that of a forest because it would soak up more of the radiation becuase its lighter and less shaded. b/c -white rock would lower the albedo becuase of its light colour. d/e- tar would take longer to cool down because of its dark colour meaning that it reatians heat for a longer period of time. f-conduction is the transfer of heat so in an urban heat island, conduction would transfer the heat. g-Convection is the transfer of heat within a fluid so, in an urban heat island convection would transfer the heat within the liquids

Lab 12-1c pg 515** Analyze 1.I found that north and south america were the easiest to fit together. They had the best shape to fit. 2.All the pieces of evidence led me to believe Pangea really existed, they all worked together to to form the idea of Pangea. 3.a-I found madagascar difficult to place as it was small and didnt really have a place. b-It would of been better if it had a better shape. Conclude and Apply 1.a-I first cut out the pieces, then i used the evidencec provided and the shape of the continents to put the pieces together. b-I used the shape of the continents to estimate where they continents could go. 2. If i had used only one piece of evidence to put together Pangea, I would have gotten innnacurate results like the wrong continent inthe wrong place. 3.a-I think they continents will be even farther away in 200 million years, they might even collide on the oppostie side. b-The continents could float to a different place on the earth, which would change the climate and temperature.
