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?

iron is a better conductor of heat than lead.
lead is a better conductor of heat than iron.
lead has a higher heat capacity than iron.
iron has a higher heat capacity than lead.

The correct answer would be "Iron has a higher heat capacity than lead".

Heat capacity can be defined as the amount of heat transferred required in order to raise the temperature of an object by 1°.

The higher the heat capacity the more the heat transfer is required to raise the temperature.

Iron has higher heat capacity as compared to the lead due to which it requires more heat transfer to raise the temperature of the iron as compared to the lead.

It is why the temperature of the lead increases more as compared to iron even though they absorbed the same amount of thermal energy.
