An iron rod and a copper rod of equal length are each held by hand at one end, with the other end in the flame from a Bunsen burner. The copper rod becomes too hot to hold much sooner than the iron rod. What does this information tell you about iron and copper?

Answer:

Iron has a higher heat capacity than copper

Explanation:

The heat capacity of a substance is defined as the amount of heat required to raise the temperature of an object by 1°C.

The higher the heat capacity of a substance, the longer the time it takes for the substance to become hot when heated.

Since the copper rod becomes too hot to hold much sooner than the iron rod, it means that iron has a higher heat capacity than copper.
