An inexpensive food and beverage container is fabricated from 25-mni-thick polystyrene (k = 0.023 w/m k) and has interior dimensions of 0.8 m times 0.6 m times 0.6 m. under conditions for which an inner surface temperature of approximately 2 degree c is maintained by an ice-water mixture and an outer surface temperature of 20 degree c is maintained by the ambient, what is the heat flux through the container wall? assuming negligible heat gain through the 0.8 m times 0.6 m base of the cooler, what is the total heal load for the prescribed conditions?
