Professor Whitney has a sample of lead and a sample of iron. The samples have equal mass. When Whitney heats the samples, the lead reaches a higher temperature than the iron, even though both samples absorbed the same amount of thermal energy. What can Whitney conclude from this experiment? A. Iron is a better conductor of heat than lead. B. Lead is a better conductor of heat than iron. C. Lead has a higher heat capacity than iron. D. Iron has a higher heat capacity than lead.
