A hailstone (frozen water) of diameter 7 cm (at melting point temperature) falls into a lake...
A hailstone (frozen water) of diameter 7 cm (at melting point temperature) falls into a lake with a water temperature of 25degreeC, and floats in the water 1 m beneath the water surface. What is the heat loss into the hailstone from the surrounding water just after the stone entered it? Assuming the heat loss value remains constant, roughly estimate how long it would take for 30% of the hailstone to melt.
