A 5 cm high rectangular ice block (k = 2.22 W/mo C and a = 0.124´10-7 m2 /s) initially at -20o c is placed on a table on its square base 4cm´4cm in size in a room at 18o C. The heat transfer coefficient on the exposed surface of the ice block is 12 W/m2oC. Disregarding any heat transfer from the base to the table, determine how long it will be before the ice block starts melting. Where on the ice block will the first liquid droplet appear
