Solve the all parts of given problem:

Problem: Consider a double-paned window consisting of two panes of glass, each with a thickness of 0.500 cm and an area of 0.660 m2, separated by a layer of air with a thickness of 1.60 cm. The temperature on one side of the window is 0.00° C; the temperature on the other side is 20.0° C. In addition, note that the thermal conductivity of glass is roughly 36 times greater than that of air.

Part I: Approximate the heat transfer through this window by ignoring the glass. That is, calculate the heat flow per second through the 1.60 cm of air with a temperature difference of 20.0° C. (The exact result for the complete window is 19.0 J/s.) Express your answer with three significant digits. Answer in J/s

Part II: Use the approximate heat flow found in part (a) to find an approximate temperature difference across each pane of glass. (The exact result is 0.171°C.) Express your answer with three significant digits. Answer in Celsius

Show all work, use additional paper if necessary.
