To defog the rear window of an automobile, a very thin transparent heating element is attached to the inner surface of the window. A uniform heat flux of 1300 W/m2 is provided to the heating element for defogging a rear window with thickness of 5 mm. The interior temperature of the automobile is 22°C and the convection heat transfer coefficient is 15 W/m2·K. The outside ambient temperature is -5°C and the convection heat transfer coefficient is 100 W/m2·K. If the thermal conductivity of the window is 1.2 W/m·K, determine the inner surface temperature of the window.
