Fouriers law of heat conduction states:

A Q = hAΔT

B q = −k(dT/dx) (heat flux proportional to negative temperature gradient)

C Q = εσT⁴

D Q = mcΔT

✓ Correct Answer: Option B

Fouriers law: q = −k(dT/dx). Negative sign indicates heat flows from high to low temperature.

💡 Why is B) the correct answer?

The correct answer to the question "Fouriers law of heat conduction states:" is Option B: q = −k(dT/dx) (heat flux proportional to negative temperature gradient).

The other options — A) Q = hAΔT, C) Q = εσT⁴, D) Q = mcΔT — are incorrect for this FE Exam Prep question. As explained above: Fouriers law: q = −k(dT/dx). Negative sign indicates heat flows from high to low temperature.
