Question:
A 5 cm diameter spherical piece of ice (spherical shape) was taken from the refrigerator at 0 C and placed on a grid at room temperature T=20 C. Express the diameter of the ice as a function of time after it is removed from the refrigerator and calculate the change in diameter with time. The heat transfer coefficient h for a sphere in a still room is approximately 3 W/m.K. Assume that the temperature inside the sphere does not change and is constant at 0 C.
