Mia and Devon are having a summer party. They need to make two sizes of ice. The large blocks of ice will be put in a cooler to keep cans of soda cold. The small ice cubes will keep the sodas in the glasses cold. They wondered how the temperature at which water freezes is affected by the size. Which statement below is true?
A. Small ice cubes freeze at a lower temperature than large blocks of ice.
B. Small ice cubes freeze at a higher temperature than large blocks of ice.
C. Small ice cubes and large blocks of ice freeze at the same temperature.

Or to cool it down
Change of StateChange of State Water exists in the liquid
state in a very wide range of temperatures
Form 0oC to 100oC In liquid form all over the
world
Change of StateChange of State Water has extreme
boiling/freezing points Boiling point: 100o C, 212o FFreezing point:0o C, 32o F
