Why hot water dissolves food coloring faster than cold water?

Answer 1

I just did an experiment on this actually.

Water molecules travel faster in hot water than in cold water. When food dye is added into hot water where the molecules are traveling faster, it mixes faster. In cold water, the particles are not traveling as fast and the food dye does not spread as fast.

Answer 2

because the water molecules have more energy and they let the food coloring fit into the gaps they make. But the cold water has less energy and the water molecules are closer so the food coloring cant dissolve

Answer 3

water with food coloring. just did that for science experiment.

I am 100% sure, that it's the darker ones.
