How many drops of food coloring you need to make brown depends on the shade you are trying to achieve. Begin by using two drops or red, two drops of yellow, and two drops of blue. You can then add one or more drops of each to achieve the shade you desire.
You cannot use yellow and green food coloring to make blue. Blue is a primary color so you cannot obtain it by mixing other colors. Yellow and green will make a lighter green.
One drop of red and two or more drops of yellow
Who knows, it depends on what kind of green you want. Or just use your brain and look on the back of the food coloring box!
It depends on many factors, such as how big the glass is, how much water is in the glass, the amount of food coloring added, and the temperature of the water.
When you put a drop of food coloring into a glass of water, the water will turn that color.
It depends on temperature. The warmer the liquid the faster diffusion occurs.
If you want to get the answer, you should do the experiment instead of going on Google to find the answer!
because of a chemical reaction that causes the cup to melt a little and the color soaks in.
Usually you cant, but if the flower is white you can put it in glass with water and pour food coloring in the water. After a few days the flowers will be the color of the water.
The solvent is the larger amount in this case (water).
the food coloring slowly moves around in the glass (like smoke would) and that is happening because the particles in the food coloring are not use to the temperature of the water,but as the particles get use to the temperature they move a little faster and spread everywhere in the water. Slowly disperse throughout the water, this is because of diffusion.
because the water is clear and when the coloring is mixed in, it takes on that color
A good question might be, "How long does it take a drop of food dye to color a glass of still water?"
no
food coloring is made up of many substances such as water and dye. The color of the dye is the color of food coloring.
This is the diffusion of the coloring agent molecules in water.
