A skyscraper has 550 windows that each have length 2.50m and height 2.0m when the temperature is 25C. the windows are made of single-pane glas of thickness 1/2"(1.27com) mounted in an aluminum frame. the coefficient of linear thermal expansion for glass is 9*10^-6 C. and the coefficient of linear thermal expansion for aluminuim is 24*10^-6 C. the thermal conductivity for glass is 0.96J/(s.m.K)

On the cold day(-10C) what are the lengths of the glass window and the aluminuom frame?what is the difference between these lengths in mm?
