The specific heat of copper is roughly three times as great as the specific heat of gold. Which of the following is true? The melting temperature of copper is roughly three times that of gold. If the same amount of heat is applied to equal masses of gold and copper, the copper will get hotter. Copper heats up three times as fast as gold. A piece of copper stores three times as much heat as the same mass of gold at the same temperature.
