a 1 m-wide by 2 m-high window is composed of two 5 mm-thick glass panes, seperated by an air space of 10 mm. the temperature at the inner and outer surfaces of the window are 15 C and -20 C respectively. If the thermal conductivities of the glass pane and the air space are 1.4 w/m-k and 0.024 w/m-k, respectively. find the total conduction thermal resistance of the window in k/w
