The rear window of an automobile is defogged by passing warm air over its inner surface. If the warm air is at Ti = 40°C and the corresponding convection coefficient is h; = 30 W/m2-K, what are the inner and outer surface temperatures, in °C, of 4- mm-thick window glass, if the outside ambient air temperature is T,0 = -30°C and the associated convection coefficient is ho = 65 W/m2-K? Evaluate the properties of the glass at 300 K. °C °C

Answer correctly and quickly as possible please.

The rear window of an automobile is defogged by passing warm air over its inner surface. If the warm air is at Ti = 40°C and the corresponding convection coefficient is h; = 30 W/m2-K, what are the inner and outer surface temperatures, in °C, of 4- mm-thick window glass, if the outside ambient air temperature is T40 = -30°C and the associated convection coefficient is ho = 65 W/m2-K? Evaluate the properties of the glass at 300 K. Tsi = °C Tso = i °C
