Which statement below explain why many small ice cubes would melt faster than one very large ice cube?

• smaller ice cubes have less surface area touching the liquid water so more thermal energy is transferred from the ice to the water

• smaller ice cubes have more surface area touching the liquid water so more thermal energy is transferred from the water to the ice

• a large ice cube has more surface area touching the liquid water so more thermal energy is transferred from the water to the ice

• a large ice cube has more surface area touching the liquid water so more thermal energy is transferred from the ice to the water

Josie wants to collect data on how the average kinetic energy of the liquid water molecules in the ice baths changes during the experiment. Which statement BEST describes a change to the ice bath experiment that will help the students collect this data?

• Measure the water height in each ice bath throughout the experiment and compare the initial and final water heights.

• Measure the water volume in each ice bath throughout the experiment and compare the initial and final water volumes.

• Measure the size of each piece of ice in each ice bath throughout the experiment and compare the initial and final sizes of each piece of ice.

• Measure the water temperature in each ice bath throughout the experiment and compare the initial and final water temperatures.
