Thermal conductivity is directly proportional to the square root of temperature and inversely proportional to the square root of the molar mass.
Formula:
K = (QL)/(AΔT),
Where,
- 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.
- ΔT is the difference in temperature in Kelvin.
