You have three pans. One is made of Iron, another of aluminum and the third of copper. Each pan requires a different amount of energy to raise the temperature o 1 g of the metal in it by 1^o Kelvin. The aluminum pan requires 0.897 J of energy, the iron pan requires 0.449 J and the copper pan requires 0.385 J . All three pans have the same Mass, which pan will exhibit the least temperature change when 50.00 J of energy are transferred to it?

• Aluminum

• Copper

• Iron

• they will all have the same temperature
