A can of soft drink, 12-cm high and 6-cm diameter, is initially at 20°C. It is placed in a refrigerator where the air is at 0°C. The convective heat transfer coefficient associated with the outer surface of the can is 10 W/m2 °C. Assuming the properties of the drink to be those of water and that the heat capacity of the container is negligible, estimate the time taken for the temperature of the drink to reach 5°C.
