Which element is likely to have the highest thermal conductivity?
antimony
carbon
sodium
gallium

Answer is: sodium.

Thermal conductivity is the property of a material to conduct heat.

In the International System of Units (SI), thermal conductivity is measured in watts per meter-kelvin (W/(m⋅K)).

Metallic bond increace electrical and thermal conductivity.

Thermal conductivity of sodium is 140 W/(m·K).

Thermal conductivity of antimony is 24 W/(m·K).

Thermal conductivity of gallium is 40 W/(m·K).

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.
