Question

Heat transfer by conduction is described by

• A. Fourier’s law
• B. Fick’s law
• C. Newton’s law of cooling
• D. Stefan-Boltzmann law

Hint:

Fourier's law applies to solids and stationary fluids for conduction heat transfer.

Answer 1

The Correct Option is A

Fourier’s law relates heat flux to the temperature gradient:
\[ q = -k \frac{dT}{dx} \]
It describes the rate of conduction through a medium.
