Given:

Four metal samples having the same temperature change and the same mass.

The specific heat of platinum is 130 J/kg deg C

The specific heat of copper is 390 J/kg deg C

The specific heat of aluminum is 900 J/kg deg C

The specific heat of silver is 230 J/kg deg C

Required: To choose the metal that will cool the fastest.

Step-by-step explanation:

The metal with the lowest specific heat will cool the fastest.

Thus, the platinum will cool the fastest.

Final Answer: Platinum
