Question

Consider one-dimensional steady state heat conduction along x-axis $$\left( {0 \le x \le L} \right),$$ through a planewall with the boundary surfaces $$(x=0$$ and $$x=L)$$ maintained at temperatures of $${0^ \circ }C$$ and $${100^ \circ }C$$. Heat is generated uniformly throughout the wall. Choose the CORRECT statement.

Accepted Answer

The maximum temperature inside the wall must be greater than $${100^ \circ }C$$.

Answer

The direction of heat transfer will be from the surface at 100°C to the surface at $${0^ \circ }C$$.

Answer

The temperature distribution is linear within the wall.

Answer

The temperature distribution is symmetric about the mid-plane of the wall.
