Question

A block of ice, mass 24kg, is placed inside a
closed cubical thin walled box having
dimension 1m. Water from melting ice
collects in the bottom of box. If ice block is
at 0°C and outside temperature is15°C.
Temperature of interior of box is to remain
at 0°C for exactly 24 hours untill all the ice
melts. Assume that liquid water formed by
melting ice remains at0°C, heat conduction
takes place from all the surface. Latent heat
of fusion of water = 360 kJ/kg, Thermal
conductivity of material of wall = 0.01W/m-
K. Neglect heat capacity of the box. What is
least thickness of the box (in mm)​
