Silver is the best conductor of heat and will require the least amount of energy to heat it by 1⁰C.
What is specific heat capacity?
The specific heat capacity of an object is the quantity of heat require to raise a unit mass of the substance by 1 kelvin.
The specific heat of the given substances;
Water = 4186 J/kg⁰C
Copper = 385 J/kg⁰C
Concrete = 850 J/kg⁰C
Iron = 450 J/kg⁰C
Silver = 233 J/kg⁰C
Air = 1005 J/kg⁰C
The material that will require the least energy to heat it by 1 ⁰C is a material with the highest thermal conductivity and least specific heat capacity.
Thus, silver is the best conductor of heat and will require the least amount of energy to heat it by 1⁰C.
