Thermal Energy and Chemical Change Lab Report Instructions: In this engineering lab, you will build and test a device that releases and absorbs thermal energy in order to reach a goal. You will need to repeat tests of your device to make sure it does not need to be redesigned or improved. Record your observations and test measurements in the lab report below. You will submit your completed report.

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
