Solution

SI unit of thermal conductivity

  1. The capacity of a material to transport thermal energy or heat energy via itself is known as thermal conductivity. It is denoted by k.
  2. Heat moves from one conductor face to another as a result of temperature difference.
  3. The expression for thermal conductivity is given as k=Q·LA·T, where, Q denotes the amount of heat energy that can be transferred through the given material in the units of power, L represents the length of the conductor, Arepresents the area of cross-section of the conductor and T represents the temperature difference between the two ends of the conductor.
  4. In SI system, unit of Q is Watt denotes as W, unit of L is Meter denoted as m, unit of A is square meter denoted as m2, unit of T is Kelvin denoted as K. Therefore, the SI unit of thermal conductivity is Wmm2KWmK i.e. Watt per meter Kelvin.

Hence the SI unit of thermal conductivity is Watt per meter Kelvin.
