Calculate how long it will take for the ice to melt??
A chilly bin has walls 5.90 cm thick and the total area of the walls is 0.700 m2. The chilly bin is loaded with 2.00 kg of ice at 0.00 °C and stood on a rack so that its entire surface is in contact with the air. The temperature on the outside of the chilly bin is 28.0 °C. If the chilly bin is made of styrofoam (kstyrofoam = 0.0100 J s–1 m–1 °C–1), how many hours will it take to melt all of the ice?
(Note: Lfwater = 3.35 × 105 J kg–1)
I was given (L (water) x m (water))/ kA(Change in T/Change in thickness)
But it didnt work out right
Answer is: 56 hours
I have no idea how to get to this :(
