Question

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?

Answer 1

The temperature increase of a substance is T=Q/m*c, where m is the mass, Q is the energy absorbed and c is the specific heat.  So you can conclude that if the lead gets to a higher temperature, it must have a lower specific heat
