The specific heat capacity of iron is approximately half that of
aluminum. Two balls of equal mass, one made of iron and the other
of aluminum, both at 80 °C, are dropped into a thermally insulated
jar that contains an equal mass of water at 20 °C. Thermal
equilibrium is eventually reached. Which one of the following
statements concerning the final temperatures is true?
A. Both balls will reach the same final temperature.
B. Iron ball will reach higher final temp than aluminum ball.
C. Aluminum ball will reach higher final temp than iron ball.
D. Diff in final ball temps depends on initial mass of water.
E. Diff in final ball temps depends on initial temp of water.
