Question:easy

\(q = -k A \frac{\Delta T}{\Delta x}\) is called as

Show Hint

Fourier's Law is the governing equation for heat conduction:
\[ q = -k A \frac{dT}{dx} \]
The negative sign is physically necessary because heat naturally transfers down a negative temperature gradient (from high to low temperature).
