Bobby Drake aka “Iceman” is member of the X-Men who has the physics-defying ability to “manipulate cold and ice.” Iceman is depicted with the ability to lower the temperature of nearby objects at will. For example, Iceman can freeze an entire pond in seconds just by touching the surface of the water. Let’s put some numbers to this example: The pond is 20 m across and can be approximated as a hemisphere. You can assume the density of water is 1.00 g cm–3 and independent of temperature. The temperature of the pond is initially 17°C and uniform throughout. After Iceman freezes the pond, its temperature is –10°C a) How many moles of water are in the pond? b) What is the total amount of heat removed from the pond?
