Question

. A drop of food coloring spreading out in a cup of water is an example of which transport process?

Answer 1

Molecules in a gas have lots of energy and spread out even more than molecules in a liquid. Warm water has more energy than cold water, which means that molecules in warm watermove faster than molecules in coldwater. The food coloring you add to the water is pushed around by the water molecules. This happens due to the process of diffussion.
