what are the effect of thermal conductivity on temperatue\re?

Answer 1

The more the thermal conductivity of a body, the lesser time it takes to attain uniform temperature all over its volume.

Answer 2

Actually the question should be put the other way. What is the influence of temperature on thermal conductivity. Thermal conductivity of a substance is not a constant, just like its density. With increase of temp generally the dimensions increase, so the density reduces. But with thermal conductivity the answer is not so simple. With most metallic substances the thermal conductivity reduces with increase in temperature just like its electrical conductivity. But with gases and also with semi conductors the conductivity increases with increasing temp.

Answer 3

If two objects at different temperature form a closed system and there is some thermal contact between both (heat flow exists) then the effect is to reduce the temperature difference between them. (Second law of thermodynamic).

Answer 4

Generally the effect is to bring the temperatures of two touching objects to equality. The more conductivity between them the faster they approach equality. The formula for conduction through an object is
dQ/dt = k*a*dT/dx, where
dQ/dt is heat flow (e.g., in watts w)
k is thermal conductivity (a property of the material, not its size or geometry; e.g., in w/(deg. K*m))
a is the cross-sectional area of the heat flow (e.g., in m^2)
dT/dx is the temperature gradient (e.g., in deg. K/m)
Incidentally the R value, a figure of merit for insulation of a given thickness, equals thickness/k (e.g., in deg. K*m^2/w consistent with the units above, but actually deg. F*ft^2*hours/BTU in practice).

Answer 5

thermal conductivity is directly proportional to the temperature.

Answer 6

it depends on 2 factors the conductivity of the material and the temperature of the body.
