Heat is generated uniformly throughout the wall. Choose the CORRECT statement

Question

Consider one-dimensional steady state heat conduction along x-axis (0$\leq$x$\leq$L), through a plane wall with the boundary surfaces (x=0 and x=L) maintained at temperatures of 0⁰C and 100⁰C. Heat is generated uniformly throughout the wall. Choose the CORRECT statement.                                                               

      (a) The direction of heat transfer will be from the surface at 100⁰C to the surface at 0⁰C

      (b) The maximum temperature inside the wall must be greater than 100⁰C

      (c) The temperature distribution is linear within the wall

      (d) The temperature distribution is symmetric about the mid-plane of the wall
