The amount of heat flow through a body
by conduction is
चालन द्वारा किसी पिंड से प्रवाहित ऊष्मा की मात्रा है
Directly proportional to the surface
area of the body
Directly proportional to the
temperature difference on the two faces of the body
Dependent upon the material of the
body
All options are correct
All options are correct
The amount of heat flow through a body
is directly proportional to the surface area of the body, directly proportional
to the temperature difference on the two faces of the body and it depends upon
the material of the body.
We can identify this by the help of Fourier’s law of conduction
In this equation we can observe that
Heat flows directly proportional to area
Heat flow is directly proportional to
temperature difference
Heat flow is directly proportional to
thermal conductivity
Hence, the correct option is (D).
