The food coloring will mix the fastest in the hot water because the molecules are moving fast due to their increased thermal energy. These fast-moving molecules are pushing the molecules of food coloring around as they move, causing the food coloring to spread faster.

Use about 20 to 30 drops of food coloring per half-cup of warm water. Set the damp stem of the flower in the colored water. The petals should become colored after a few hours. It may take as long as 24 hours, however, depending on the flower.

Food dye can change the color of flowers when you put it in the plant’s water. Plants lose moisture through the tiny pores in their leaves. The longer the plants remain in the water, the darker the flowers become. If using cut flowers, the dye may even eventually flow back into the water, giving it additional tint.

Observence after adding the food coloring A visible tasty food is more likely to get the attraction of the eater. When a certain food colour is added or say food colouring is done the food item on which it is done turns up into to the colour that we have added which can or cannot be achieved by simple cooking.

It takes about 30 seconds for the food coloring to dissolve in the hot water. The actual dispersion activity should not run longer than two minutes.

Answer: -the food coloring drops on the water, as it drops, it spreads throughout the bottle smoothly. – when it spreads, it’s starting to loss its color. – when dropped on the water, it spreads in any direction.

In hot water, the food coloring diffuses (spreads out) through the water quickly. In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster.

THE FOOD COLORING IS TRANSFER OF HEAT.

Yes it spread faster in water. Because in hot water,the water molecules have more energy and are moving faster than the molecules of cold water.

Food coloring illustrates diffusion in water. Diffusion is the mixing of molecules due to their random motion, whether in a liquid or a gas. Because molecules in cold water have less kinetic energy than in warm water, the diffusion process is much slower than in warm water.

If there are any particles suspended in the water, they will increase the scattering of light. In coastal areas, runoff from rivers, resuspension of sand and silt from the bottom by tides, waves and storms and a number of other substances can change the color of the near-shore waters.

Molecules in a liquid have enough energy to move around and pass each other. Warm water has more energy than cold water, which means that molecules in warm water move faster than molecules in cold water.

The molecules of cold water are moving slower and are a little closer together. If students do not notice a difference, move the slider all the way to the left again and then quickly to the right.

Because it takes cold water some time to reach the temperature of hot water, cold water clearly takes longer to boil than hot water does. “It all depends on how fast the cooling occurs, and it turns out that hot water will not freeze before cold water but will freeze before lukewarm water.
