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 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 temperature of sample 2 is higher.
The temperature of sample 2 is higher.
The water molecules of sample 1 are transferring more kinetic energy.
1 answer
The statement that best explains the observations in the table is:
The temperature of sample 2 is higher.
This explanation aligns with the fact that when the temperature of water increases, the water molecules move faster, causing the food coloring to spread more quickly in sample 2 compared to sample 1.
