Question

What is called thermal conductivity ?​

Answer 1

Answer:

Hi friends

Explanation:

Thermal conductivity is expressed in terms of the following dimensions: Temperature, Length, Mass, and Time. The SI unit of this quantity is watts per meter-Kelvin or Wm-1K-1. ... These units describe the rate of conduction of heat through a material of unit thickness and for each Kelvin of temperature difference.

Answer 2

Answer:

mark me brainliest pls

Explanation:

Thermal conductivity can be defined as the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area
