The inner and outer surfaces of a 0.5 cm thick x 2.0 m x 2.0 m window glass in winter are 12°C and 4°C, respectively. If the thermal conductivity of the glass is 0.78 W/m-°C, determine the amount of heat loss, in kJ, through the glass over a period of 12 h. What would the answer be if the glass were 1.5 cm thick?
