The students observed that the smaller ice cubes in Ice bath 2 melted faster than the larger ice cube block in Ice bath 1. Based on the ice bath setup in Figure 1, which statement best explains why several smaller ice cubes melt faster than larger block of ice? Please help 1. Measure the water height in each ice bath throughout the experiment and compare the initial and final water heights. 2. Measure the water volume in each ice bath throughout the experiment and compare the initial and final water heights. 3. 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. 4. Measure the water temperature in each ice bath throughout the experiment and compare the initial and final water temperature.
