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 close to freezing.
The temperature of sample 2 is close to freezing.
The water molecules of sample 1 are moving faster.
The water molecules of sample 1 are moving faster.
The water molecules of sample 1 are transferring more kinetic energy.
The water molecules of sample 1 are transferring more kinetic energy.
The temperature of sample 2 is higher.

The statement that best explains the observations in the table is:
The temperature of sample 2 is higher.
This is because a higher temperature typically results in faster-moving water molecules, which would cause the drop of food coloring to spread quickly in sample 2. In contrast, if sample 1 had a lower temperature, the food coloring would spread more slowly. The other options are not consistent with the observations made.
