To ensure effective heat transfer from the food inside a freezer, the 2-mm thick layer of frost that formed at its inside surface must be melted. The compartment is in ambient air at 20°C W kg and a coefficient of h=2- characterizes heat transfer by natural convection from the exposed surface of the layer. The frost is at its melting point, has a density of 700 and a m².K kJ kg latent heat of fusion of 334 Based on what is given in this problem, is it possible for you to compute how long it will take for the entire frost to melt? O Yes. All information needed for the computation is given O No. Some crucial information for the computation is not given. O This option is blank. O This option is blank. m
