The figure given below shows the variation of temperature across the thickness of materials with different thermal conductivities under steady states. CurveCwill be applicable when thermal conductivity of the material.
Increases with increase in temperature
Decreases with increase in temperature
is very large
is constant at all temperatures
is very large
If thermal conductivity of the
material is very large it will allow heat to transfer instantly and temperature
would be almost same all along the thickness.
