A Thermally Isolated System Is Made Up of a Hot

A thermally isolated system is made up of a hot piece of aluminum and a cold piece of copper; the aluminum and the copper are in thermal contact. The specific heat capacity of aluminum is more than double that of copper. Which object experiences the greater temperature change during the time the system takes to reach thermal equilibrium?

A) the aluminum
B) Neither; both experience the same size temperature change.
C) It is impossible to tell without knowing the masses.
D) the copper
