Question

Define co–efficient of thermal conductivity and hence find its unit in SI.

Answer 1

Answer:

Coefficient of thermal conductivity : The coefficient of thermal conductivity of a material is defined as the quantity of heat that conducts per unit time through a unit cube of the material when its opposite faces are kept at a temperature difference of one degree. SI unit : J s-1 cm-1 oC-1 or W m-1K-1.
