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 water molecules of sample 1 are moving faster.
The water molecules of sample 1 are moving faster.
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 best explanation for the observations in the table is:
The temperature of sample 2 is higher.
This is because if the food coloring spreads very quickly in sample 2, it suggests that the molecules in that sample are moving faster, which is typically a result of higher temperature. Conversely, the slower spread in sample 1 indicates lower temperature and slower molecular movement.
