The rear window of a van is coated with a layer of ice at O°C. The density of ice is 917 kg/m³, and the latent heat of fusion of water is
3.35 x 105 J/kg. The driver of the van turns on the rear-window defroster, which operates at 12 V and 19 A. The defroster directly
heats an area of 0.36 m² of the rear window. What is the maximum thickness of ice above this area that the defroster can melt in 2.3
minutes?
