Responses

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

The water molecules of sample 1 are moving faster.

Answer 1

The temperature of sample 2 is higher.

Higher temperature means water molecules have more kinetic energy and move faster, so the food coloring diffuses more quickly.
