Melting Icebergs
Icebergs often form when large pieces of ice from land-based ice sheets and glaciers break off into the surrounding ocean water. These icebergs can have many shapes and sizes, ranging from only sixteen feet across to as wide as a small country. The number of icebergs in an ocean at any one time also varies. Scientists studying icebergs have observed that smaller icebergs melt at different rates than larger icebergs.
A group of students designed a classroom investigation to study the melting process for ice pieces of different sizes. They will use their results to build a model explaining why icebergs with different sizes melt at different rates.
For the experiment, the students started with an ice block that had the same total mass of ice as several ice cubes. The students placed the ice block and ice cubes in separate containers with water. The water in both containers started at the same temperature. They then measured the amount of time needed for the large block of ice and several smaller ice cubes to melt. The experiment setup for the ice baths is shown in Figure 1. The date in the table shows the starting conditions of the experiment just as the ice was added to the water.
Question
The students want 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?
A Measure the water height in each ice bath throughout the experiment and compare the initial and final water heights. Measure the water height in each ice bath throughout the experiment and compare the initial and final water heights.
B Measure the water volume in each ice bath throughout the experiment and compare the initial and final water volumes. Measure the water volume in each ice bath throughout the experiment and compare the initial and final water volumes.
C 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 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.
D Measure the water temperature in each ice bath throughout the experiment and compare the initial and final water temperatures. Measure the water temperature in each ice bath throughout the experiment and compare the initial and final water temperatures.
