Fill in temperatures at each position (ambient, surface, and probe) in excel table provided for both free and forced convection. 2. Reference Chart in Excel Document. 3. Note the difference in gradient between free and forced convection for each surface. 4. Do the results match the conclusions from earlier experiments? 5. The extended surfaces are made of stainless steel, which is a relatively poor conductor. How would using aluminum or Copper (better conductors) affect the temperature gradient and overall efficiency
