Answer:
The layering and mixing effect of ice cubes in salt water and fresh water respectively.
Step-by-step explanation:
This test helps to explain the melting of ice cubes which is more obvious when colored ice cubes are used, as it reveals the layering and mixing effect of ice cubes in salt water and fresh water respectively.
The mixing effect shows that ice cubes melt faster in fresh water (low density) than in salt water(high density).
