A Piece of Iron (C = 0

A piece of iron (C = 0.449 J/g°C) and a piece of gold (C = 0.128 J/g°C) have identical masses.If the iron has an initial temperature of 468 K and the gold has an initial temperature of 328 K,which of the following statements is TRUE of the outcome when the two metals are placed in contact with one another? Assume no heat is lost to the surroundings.

A) Since the two metals have the same mass, the final temperature of the two metals will be 398 K, exactly halfway between the two initial temperatures.
B) Since the two metals have the same mass, but the specific heat capacity of gold is much smaller than that of iron, the final temperature of the two metals will be closer to 328 K than to 468 K.
C) Since the two metals have the same mass, the thermal energy contained in the iron and gold after reaching thermal equilibrium will be the same.
D) Since the two metals have the same mass, the thermal energy contained in each metal after equilibrium will be the same.
E) None of the above is true.
