Dear Lipun,

The ability of the body to allow the flow or transfer of heat is called Thermal Conductivity.

Regards.

In physics, thermal conducticity(often denoted k, λ, or κ) is the property of a material to conduct heat. It is evaluated primarily in terms of Fourier''s Law for heat conduction.

Heat transfer occurs at a higher rate across materials of high thermal conductivity than across materials of low thermal conductivity. Correspondingly materials of high thermal conductivity are widely used inheat sink applications and materials of low thermal conductivity are used as thermal insulation. Thermal conductivity of materials is temperature dependent. The reciprocal of thermal conductivity is called thermal resistivity.

CONDUCTIVITY  WHICH CAUSED BY TEMPARATURE IS CALLED THERMAL CONDUCTIVITY.
