because the cohesion of water molecules is less stronger than the adhesion of the water molecules
The slt is dissolving into the water
It depends on temperature. The warmer the liquid the faster diffusion occurs.
The spread of a drop of food dye throughout a glass of milk is called
It travels through the air by diffusion, which is the process of a chemical transferring from an area of high concentration to low concentration. As this process occur, the 'smell' moves around the house until it is equally spread throughout the closed area (in this case the house). This is known as reaching equilibrium.
mechanical weathering
You should try it and see. Go to the kitchen, get a clear glass of water, and add a drop of food colouring to it. Or ink, if you have it. It's probably how quick the ink spreads through the water
because the force of cohesion of water is far less than the force of adhesion between the molecules of water and the glass top
Ink is spreaded faster.
When you put a drop of food coloring into a glass of water, the water will turn that color.
the water is sweetened
that is because the walls of the plate are keeping the water from coming in the plate. How ever if you drop a plate down in the water hard, it is going to sink. Put it gently in the water
It will melt.
You would see the drop slowly spread out until eventually the entire glass of water would be colored.
The slt is dissolving into the water
A good question might be, "How long does it take a drop of food dye to color a glass of still water?"
Drop a drop of food dye in a glass of water and watch. The dye diffuses through out the water, weakening the dye and coloring the water.
lETTERS TOWARD THE CENTRE OF THE DROP WOULD APPEAR ENLARGED. dROP WORKS AS MAGNIFYING GLASS.
