1 answer
The correct response that best explains the observations in the table is:
The temperature of sample 2 is higher.
This is because the faster spreading of the food coloring in sample 2 indicates that the water molecules are moving more rapidly due to a higher temperature. Higher temperatures result in increased kinetic energy of the molecules, causing them to move faster and mix more quickly with the food coloring.
