Frying pans are good conductors of heat. A scientist developed four new materials to be used for making frying pans. He made rods of equal mass and length from each material. He tested their heat conductivity by exposing one end of each rod to the same amount of heat over the same duration of time. He measured the temperature change at the other end of the rod. The data he collected is shown in the table below.

Based on the data collected, select the name of the substance that would make the best frying pan.

Original Temperature Final Temperature

Material A 20°C 27°C

Material B 20°C 37°C

Material C 20°C 21°C

Material D 20°C 35°C

Material B would be my answer ... to go from 20 to 37 C is a 17 C rise, so the heat gets to the place it's wanted best ... C would be the worst with 11 C rise ...
