Unreasonable Results

(a) Calculate the rate of heat transfer by conduction through a window with an area of 1.00m2 that is 0.750 cm thick, if its inner surface is at 22.0ºC and its outer surface is at 35.0ºC.

(b) What is unreasonable about this result?

(c) Which premise or assumption is responsible?

Expert Solution
Step 1

Given. the rate of heat transfer H by conduction through a window with an area of A=1.00 m2 that is L=0.750 cm=0.0075 m thick, if its inner surface is at TC=22.0 ºC=295 K and its outer surface is at TH=35.0ºC=308 K.

(a) To determine heat transfer H.
