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,with the aluminum and the copper in thermal contact.The specific heat capacity of aluminum is more than double that of copper.Which object will have the greater magnitude gain or loss of internal energy during the time the system takes to reach thermal equilibrium?

A) the aluminum
B) the copper
C) Neither one; both of them will have the same size gain or loss of internal energy.
D) It is impossible to tell without knowing the masses.
E) It is impossible to tell without knowing the volumes.
