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.
Explanation:
The metal with the lowest specific heat will cool the fastest.
Thus, the platinum will cool the fastest.
Final Answer: Platinum
