The increase in height of the blue color in the mix of salt water and blue food coloring as time increased is likely due to the process of diffusion. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. In this case, the blue food coloring particles in the salt water mix are moving through the fresh water, which has a lower concentration of blue particles.
As time goes on, more and more blue particles will diffuse into the fresh water, causing the height of the blue color in the mix to increase. This process will continue until the concentration of blue particles in the salt water and fresh water reaches equilibrium, at which point the height of the blue color will no longer increase.
In summary, the increase in height of the blue color over time is likely due to the process of diffusion, as the blue food coloring particles move from the salt water mix into the fresh water.
For the salt water and blue food colouring mixed with fresh water and yellow colouring,why height of blue colour increased as the time increased?
