(a) Approximate the heat transfer through this window by ignoring the glass. That is, calculate the heat flow per second through the 1.90 cm of air with a temperature difference of 20.0 C°. (The exact result for the complete window is 21.4 J/s.) Express your answer with three significant digits.

? J/s

(b) Use the approximate heat flow found in part (a) to find an approximate temperature difference across each pane of glass. (The exact result is 0.144 C°.) Express your answer with three significant digits.

? C°
