Answer 2

Answer:

THE FORMULA FOR THERMAL CONDUCTIVITY-

K = (QL)/(AΔT)

K = (QL)/(AΔT)K is the thermal conductivity in W/m.K. Q is the amount of heat transferred through the material in Joules/second or Watts. L is the distance between the two isothermal planes. A is the area of the surface in square meters.

THE DIMENSIONAL FORMULA FOR THERMAL CONDUCTIVITY-

The dimension of thermal conductivity is M1L1T−3Θ−1, expressed in terms of the dimensions mass (M), length (L), time (T), and temperature (Θ). Other units which are closely related to the thermal conductivity are in common use in the construction and textile industries.
