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

THIS IS THE BEST ANSWER 👇

Option (c) is the correct answer.

Explanation:

Thermal conductivity is defined as the ability of a substance to transfer heat.

Metals are also known to be good conductors of heat and electricity. Therefore, they show high thermal conductivity.

While non-metals are poor conductors of heat and electricity. Hence, they have poor thermal conductivity. Therefore, antimony and carbon will have less thermal conductivity.

Sodium thermal conductivity, on the other hand, is 140 W / (mk) and gallium is 29 W / (mk).

Thus, we can conclude that a sodium element is likely to have the highest thermal conductivity of the given options.
