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)

The water molecules of sample 1 are transferring more kinetic energy.

The water molecules of sample 1 are moving faster.

The temperature of sample 2 is close to freezing.

The temperature of sample 2 is higher.
