Sample Observation
1 The drop of food coloring spreads slowly.
2 The drop of food coloring spreads very quickly.
A student places a drop of food coloring into two water samples. Her observations are shown in the table. Which statement best explains the observations in the table?
(1 point)
Responses
The temperature of sample 2 is higher.
The temperature of sample 2 is higher.
The temperature of sample 2 is close to freezing.
The temperature of sample 2 is close to freezing.
The water molecules of sample 1 are transferring more kinetic energy.
The water molecules of sample 1 are transferring more kinetic energy.
The water molecules of sample 1 are moving faster.

The statement that best explains the observations in the table is:
The temperature of sample 2 is higher.
A higher temperature in sample 2 would mean that the water molecules are moving faster, which would cause the drop of food coloring to spread quickly. In contrast, in sample 1, where the food coloring spreads slowly, the temperature is likely lower, resulting in slower-moving water molecules.
