Question

a few drops of food colouring is added to a cup of water to give it colour, is it a physical or a chemical change?

explain your answer ​

Answer 1

Answer:

3 drops of red food coloring are added to water. The dye spreads out to fill the container and does NOT settle out over time. It is a physical change IF you can separate the red from the water. It changes from a liquid into a gas (water vapor).

So mixing of food with water is basically a physical change…. Not chemical change….. ... The mixture is still h2o, only colored from the dye. Since the chemical composition is still the same it's considered a physical change.

so this is your answer
