The specific heat of gold is 0.13 J g -1 K -1 and that of copper is

Question:

The specific heat of gold is 0.13 J g-1 K-1 and that of copper is 0.39 J g-1 K-1. Suppose that we heat both a 25-g sample of gold and a 25-g sample of copper to 808C and then drop them into identical beakers containing 100 mL of cold water at 108C. When each beaker reaches thermal equilibrium, which of the following will be true, and why? (You should not need to calculate the actual temperatures here.)

(a) Both beakers will be at the same temperature.

(b) The beaker with the copper sample in it will be at a higher temperature.

(c) The beaker with the gold sample in it will be at a higher temperature.
