Heat conduction is a function of material property, temperature difference and fluid the geometry of the object. a) true b) false

a)True

Explanation:

According to Fourier's law,It states that Heat transfer is directly proportionate to the temperature gradient.For unidirectional conduction

Where q'' is the heat flux.

When This directly proportionate is remove then one constant will on that place and that constant is called conductivity of material.

So total heat transfer Q

When conductivity (K) of material is not constant

K=(a+bT)  where a,b are constant.

So from the above expression we can say that heat transfer in material will depend on temperature difference,material property and on on geometry of object.
