Question

Select one correct answer:                                                                                   [2 Marks]

the rate of heat transfer by conduction is;

Directly proportional to the temperature gradient in the direction of heat transfer

Directly proportional to the Surface

Directly proportional to the thickness of the body

All of the above

Directly proportional to the temperature gradient in the direction of heat transfer

Directly proportional to the Surface

Directly proportional to the thickness of the body

All of the above

Explanation / Answer

The rate of heat transfer by conduction is directly proportional to the temperature gradient in the direction of heat transfer.

Q = KA(dT/dx)

dT/dx is the temperature gradient.

A is the area of face, but not surface area.

K is thermal conductivity.
