Step-by-step explanation:
The subject of this question is Physics and the grade level is High School.
When calculating the rate of heat conduction through the double-paned window, we need to consider the temperature drops across the glass panes and the air gap between them. The problem states that there are identical temperature drops across the two glass panes, so we have to find those first and then calculate the temperature drop across the air gap. This problem ignores convection and focuses only on heat transfer through conduction.
