Question

Conductivity of heat is more in:
(a) Wood
(b) Iron
(c) Copper
(d) Soil

Answer 1

Answer:

copper as it is a good conductor of electricity and heat

Answer 2

Copper is the best conductor of heat among the given list.

Explanation:

Thermal conductivity of a substance is its ability to conduct heat. It is expressed in SI units of Watt Per Meter Per Kelvin (W/m-K).

Materials with higher thermal conductivity transfer heat faster than materials with lower thermal conductivity.  

In general, metals are very good conductors of heat when compared to wood. From the given list, copper as the highest thermal conductivity.
