Hot water, because it molecules are moving faster and thus the coloring will diffuse more quickly. In addition, if there is any kind of convection current (if there is a heat source) that would also speed the process.
Like when you fart, if somebody is standing near you and its a bare bum fart lets say they can taste your poo particles, so its like your pooing in their mouth. You can be all like "Hey i just pooed in your mouth".

Hot water, because particles will move faster and spread apart more than in cold water, thus making it more soluble.
Food colouring dissolves faster in hot water because the water molecules have more energy and they move around more creating larger gaps for the food colouring molecules to fit into, while the cold water has less energy and the water molecules are closser together making it harder for the food colouring to dissolve
its cold water

The food coloring will spread throughout the water and become homogeneous faster than it would in cold or warm water. The food coloring would also mix evenly with the water faster if you stirred the water after adding the food coloring. This happens because the molecules are moving faster when they are heated up stirred.

hot water
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.
Because all the molicules spread apart and stirs the food coloring and i have been told that hot water kills germs and mixes stuff better............ i love one direction
In warmer water, particles generally have more energy. This makes them move faster, and so spread out faster.
Warm Water! when molecules inside of an object heat up, the molecules go faster! which will absorbe the food coloring faster.
hot water molecules move faster with food coloring.you can experiment it with the help of following steps:-Fill the glasses with the same amount of water, one cold and one hot.Put one drop of food coloring into both glasses as quickly as possible.Watch what happens to the food coloring.If you watch closely you will notice that the food coloring spreads faster throughout the hot water than in the cold. The molecules in the hot water move at a faster rate, spreading the food coloring faster than the cold water molecules which mover
If you have the same volume of both then there are in cold water more molecules.
where did this science fair project come from?
Basic physics will tell us that higher temperatures will led to a faster rate of diffusion. The water particles will be moving faster (higher temperature = higher kinetic energy = higher particle speed), and this will lead to more particle collisions. With more, collisions, the tints will be spread quicker. A fun way to visualize this is to get 2 identical drinking glasses. Fill one with hot water, and the other with cold. Then add a single drop of food coloring to each glass at the same time. The coloring will spread quicker in the hot water.
