Answer
In accordance with the principle of specific heat capacity, we understand it that if a material has lower specific heat capacity, it will need less energy to change the temperature. Considering this, we have checked the provided data and found that Silver has the minimal specific heat capacity value among the choices. 【Answer】: Silver.
Explanation
The question essentially asks us to identify the substance that requires the least amount of heat energy to raise its temperature by one degree Celsius. This means we are looking for the smallest amount of specific heat capacity in the provided data. "Specific heat capacity" is an amount of "heat" needed to increase the temperature of 1 kg of the specific material by 1 degree of Celsius. This is quite straightforward, having a glance at the table shows us that Silver has the smallest Specific heat capacity value, 233 J/kg°C, as compared to the other materials listed.Highlight
